Print Preview (see Figure 27-8) is a separate application window and includes its own command menus, toolbars, property bar, status bar, and toolbox When Print Preview is open, CorelDRAW is still open in the background The Print Preview utility provides a higher level of control over the finished print than preferences you set in the File | Print dialog

Browsing and Viewing Previews

The first thing you’ll want to do in Print Preview is to examine how your printed pages will look Across the bottom of the Print Preview window, you’ll find page controls, shown next,

so you can browse each printed page Use the arrow buttons to move forward or backward in the sequence, or click a page tab to display a specific page As you do this, you’ll discover

Ill 27-7

You can view your pages in a number of different ways based on output mode, color,

and object type To change view modes, choose one of the following from the View menu:

● Show Image Choosing this lets you hide the display of page contents to speed

screen redraw times when you’ve got a lot of objects on a specific page

● Preview Colors Choose this to access three basic previewing states Auto

(Simulate Output) shows each page’s color according to your selected options and your printer’s capabilities If your chosen printer driver does not print in color, you’ll see only grayscale color on your pages To override this, choose either Color or Grayscale, which forces a specific view

● Preview Separations Choose Preview Separations to access three basic states

Auto (Simulate Output) displays separations according to your printer driver and selected print options If Separations are not selected to print, only a composite is shown, and vice versa You can override this by choosing either Composite or Separations to force a specific separation display state Overprints do not display accurately in Print Preview, and trapping cannot be seen

● Printable Area This varies from printer to printer; the printable area is the

physical area that the printer can render onto a page Choose this option (selected by default) to show a dotted line representing the maximum extent to which the printer can render

● Render PostScript Fills Use this option to have PostScript fills display as they

will print Deactivating this option can free up system resources when viewing documents where you used a lot of PostScript-filled objects

● Show Current Tile This option highlights individual tiles as you hover your

cursor over them when previewing, and it’s useful when printing large documents

in sections onto small output material (called tile printing, covered earlier in this

chapter) To use tile printing from within Print Preview, choose Settings | Layout to open the Print Options dialog to the Layout tab, and then click to activate the Print Tiled Pages option

Print Preview Tools and the Property Bar

The key to using Print Preview to its fullest is learning where all the options are, what each tool does, and what print properties are available while using each Four tools are on the toolbox—the Pick tool, Imposition Layout tool, Marks Placement tool, and the Zoom tool— each of which is discussed in the sections to follow The standard toolbar, shown next, contains printing options, viewing options, and shortcuts you can use to open print-related dialogs

Ill 27-8

First is the Print Style selector, which is used to choose all printing options according to

a saved set of print parameters As with other CorelDRAW Preset features, you can select, save, delete, or modify print styles in the selector Choose an existing Print Style, use the current unsaved settings on the current print job, or choose Browse to show the Open dialog

so you can work with a saved Print Style To delete a selected Print Style, click the Delete Print Style (–) button To save a Print Style, click the Save Print Style As (+) button (or use theF12shortcut) to open the Save Settings As dialog Use the Settings To Include options to specify which print options to save with your new style, and click Save to add the Print Style

to the selector

The remaining options in the standard toolbar have the following functions, many of which are covered earlier in this chapter:

● Print Options This button opens the Print Options dialog

● Print This button immediately sends the document to the printer using the current options UseCTRL+Tas a shortcut;CTRL+Pworks, too, as a common Windows command for applications that can print

● Zoom Select a predefined zoom level from the list to change the view magnification level

● Full Screen Preview This button is self-explanatory PressESCto return to Print Preview You can also useCTRL+Uas a shortcut

● Enable Color Separations This button sends the printing of color separations to

the output device using color selected in the Separations tab of the Print Options dialog

● Invert This button inverts the printed image to print in reverse This is for film

using an image-setting device, but can also provide an amusing special effect (and use a lot of ink!)

● Mirror This button flips the printed document to print backward to set emulsion

orientation on image-setting devices You can also use this to print to T-shirt transfers

● Close Print Preview Pressing this button (or using theALT+Cshortcut) returns

you to the current CorelDRAW document

Pick Tool Property Bar Options

The Pick tool in Print Preview is used in much the same way it’s used in the drawing

window; with it you select and move (by click-dragging) the contents of the current page

While the Pick tool and objects on a page are selected, the property bar features a variety of

printing options, shortcuts, position settings, and tool settings, as shown here:

Ill 27-9

Many of these options are for positioning and scaling the contents or whole pages in

relation to the printed output page size that your printer is currently set to use

Click-dragging the object control handles lets you scale the objects interactively

Imposition Layout Tool Property Bar Options

The Imposition Layout tool provides control over the print layout Only certain image setters

are capable of printing multiple pages in signature formats, so it’s best to check with the person

doing your print job before making changes using the imposition options

When the Imposition Layout tool is selected, the preview is changed to display

imposition-specific properties This tool has four separate editing states, each of which is chosen on the

Edit Settings selector Options accessible on the property bar while Edit Basic Settings is

selected, shown next, give you control over imposition layout options Choosing Edit Page

Placements, Edit Gutters & Finishing, or Edit Margins from this selector displays a set of

imposition options for each state

Marks Placement Tool Property Bar Options

The Marks Placement tool lets you alter the position of crop and fold marks, registration marks, color calibration bars, printing information, and Densitometer (density scale) positions When the Marks Placement tool is selected, the property bar features options for positioning and printing certain mark types, as shown in Figure 27-9

To position crop and fold marks, click-drag the top, bottom, or sides of the rectangle defining their position, or enter values in the property bar boxes To change the position of other marks you have selected to print with your document page, choose the Marks

Placement tool, and drag directly on the marks

Zoom Tool Property Bar Options

The Zoom tool in the Print Preview window is used much the same way as the Zoom tool in CorelDRAW, so you can increase or decrease the view of your Print Preview Many of the

You can also change Zoom settings by choosing View | Zoom (CTRL+Z) to open the

Zoom dialog to choose among all Zoom tool functions Use shortcuts to change your view

magnification while using Print Preview’s Zoom tool: Zoom Out usingF3, Zoom To Page

usingSHIFT+F4, Zoom To Selection usingSHIFT+F2, and Zoom To Fit usingF4

Print Preview doesn’t have an Undo command; to reset options quickly, click the Print Styles selector and then choose CorelDRAW Defaults All crop marks vanish, imposition settings revert, and any repositioned object reverts.

Setting Printing Preferences

Once you’re familiar with the ocean of printing options, what your output device is capable

of, and what you want from a specific print job, Printing Preferences can be your one-stop

shop for most of the items covered in this chapter Choose Settings | Printing Preferences

(CTRL+Fis the shortcut) while in the Print Preview window to open the Printing Preferences

General Printing Preferences

Options in the General tab provide control over fonts, crop mark color, driver banding, and

so on, and they set the parameters for potential preflight issues or warning dialogs that appear before and during printing These options are set by default to the highest fault tolerance for most printing jobs; 99 percent of the time your prints will come out fine if you don’t change the settings Here’s a list explaining the most common states:

● Spot Color Separations Warning This option lets you control the warning state while printing color separations The warning can be set to appear if more than one, two, three, or any spot colors are used in the document being printed

● Preview Color Default This option sets the initial color display of your printed document when the Print Preview window is first opened Choose Auto (Simulate Output), Color, or Grayscale

FIGURE 27-10 The Printing Preferences dialog offers comprehensive control over

output settings

● Preview Separations Default This option sets the initial color display of your

separations when the Print Preview window is first opened Choose Auto (Simulate

Output) or Composite

● Preview Image Default This controls whether your document image is automatically

set to show when the Print Preview window first opens Choose On At Startup (the

default) or Off At Startup

● Overprint Black Threshold (PS) During overprinting, CorelDRAW X5 sets a

default value for overprinting black objects only if they contain a uniform fill of 95

percent or more black The Overprint Black Threshold setting can be changed using

this option, so you can further customize the global overprinting function The

threshold limit can be set between 0 and 100 percent black

● Send Large Bitmaps in Chunks This option works in combination with the

Bitmap Output Threshold setting and can be set to Yes, If Larger Than Threshold

(referring to the Bitmap Output Threshold value), or No

● Bitmap Output Threshold (K) When printing to non-PostScript printers, this

option lets you set a limit on the size of bitmaps, as measured in kilobytes, sent to

the printing device By default, this value is set to the maximum, but you can set it to

specific values within a range of 0 to 4,096 (the default) This is a good option to

change if your non-PostScript printer doesn’t have a lot of memory and you’re

pulling prints that are unfinished due to lack of RAM for processing the image

● Bitmap Chunk Overlap Pixels If a printing device has insufficient memory or

another technical problem processing very large bitmap images, you can have

CorelDRAW tile sections of such a bitmap The overlap value is used to prevent

seams from showing between “chunks” of the large image When you’re printing to

non-PostScript printers, this option lets you define the number of overlap pixels

within a range of 0 to 48 pixels The default is 32 pixels

● Bitmap Font Limit (PS) Usually, font sizes set below the Bitmap Font Size

Threshold preference are converted to bitmap and stored in a PostScript printer’s

internal memory This can be a time-consuming operation that usually increases the

time your document takes to print You can limit the number of fonts to which this

occurs, forcing the printer to store only a given number of fonts per document The

default setting here is 8, but it can be set anywhere within a range of 0 to 100

Unless your document is a specimen sheet of all the fonts you have installed, 8 is

a good number to set this option to

● Bitmap Font Size Threshold (PS) Most of the time CorelDRAW converts very small

sizes of text to bitmap format when printing to PostScript printers, such as 4-point legal

type on a bottle label This option lets you control how this is done, based on the size of

the font’s characters The default Bitmap Font Size Threshold is 75 pixels, but it can be

set within a range of 0 to 1,000 pixels The actual point size converted to bitmap varies

27

according to the resolution used when printing a document The threshold limit will determine exactly which font sizes are affected For example, the equivalent font size of

75 pixels when printing to a printer resolution of 300 dpi is roughly 18 points, while at

600 dpi it’s about 9 points The higher the resolution, the lower the point size affected A number of provisions determine whether these controls apply, including whether the font has been scaled or skewed, and whether envelope effects, fountain or texture fills, or print scaling options such as Fit To Page have been chosen

● Small Fonts This controls a warning that appears if the document you’re printing includes fonts below a 7-point size threshold by default The Small Fonts warning option can be set between 3 and 18 points Resolution plays an important part in rendering small point size typefaces, as does the design of the characters within the font For example,

a 1,200 dpi laser printer can render 4-point Helvetica quite legibly, less so with a serif typeface such as Times Roman because the serifs at this size are about equal to insect parts Choose a simple sans serif font for extremely small font sizes Do not expect a perfect rendering of a very small typeface, because the dots of ink or toner cartridge can render only a finite number of dots to represent very small text

● Image Resolution Too Low By default, this value is set to 96 ppi, alerting you if bitmaps have a resolution below this value This is probably too low for even today’s personal inkjets; it’s recommended that you increase this value to at least 225 ppi

● Composite Crop Marks (PS) This is a useful feature for setting the pen color of crop marks either to Output In Black Only or to Output On All Plates—in process (CMYK) color, making the crop marks print to every color plate during process color separation printing

● PostScript 2 Stroke Adjust (PS) The PostScript Level 2 language has a provision particularly useful for graphics programs such as CorelDRAW Stroke Adjust produces strokes of uniform thickness to compensate for uneven line widths due to

the conversion of vector artwork to raster printed graphics, which is what all printers

do The PostScript 2 Stroke Adjust option should not be used for older printers that

are not compatible with PostScript Level 2 or Level 3 technology Most recently manufactured printing devices are at least PostScript Level 2 compatible If you are not sure what level your printing device is, leave this setting off or consult the docs that came with the device

● Many Fonts This controls a warning that appears if the document you’re printing includes more than ten different fonts If you’re new to CorelDRAW and are experimenting with all the cool fonts that came on the CD, your file can easily exceed this limit If your printer’s memory and/or your system resources are capable of handling large numbers of different fonts, consider increasing this value The Many Fonts warning option can be set within a range of 1 to 50 fonts Tangentially related to this option is a creative design issue: very few professionals use more than ten different typefaces in a design; five can express an idea using text quite well in most situations

● Render to Bitmap Resolution This option by default is set to Automatic, which

causes bitmaps to be output at the same resolution as vector objects and text in your

document To specify the resolution of bitmaps to be printed at lower or higher

resolutions than the rest of the document, choose specific settings within a range of

150 to 600 dpi

Driver Compatibility

The Driver Compatibility area, shown in Figure 27-11, provides control over specific driver

features for non-PostScript printers Choose a Printer from the drop-down menu, and then

choose specific options in the dialog to make changes Clicking Apply saves and associates

your changes with the selected driver

Printing Issues Warning Options

You can customize issues found by CorelDRAW’s built-in preflight feature using options in

the Preflight page of the Printing Preferences dialog (CTRL+F), which can be accessed only

from within Print Preview by choosing Settings | Printing Preferences and clicking Preflight

in the tree directory, as shown in Figure 27-12
