Fine-tune print jobs


You can fine-tune print jobs to ensure print quality. Because problems sometimes occur when you are printing text to a non-PostScript printing device (GDI printer), you can decrease printing time by specifying driver compatibility for non-PostScript printing devices. For more information, see Print colors accurately.

If a printing device has difficulty processing large bitmaps, you can divide a bitmap into smaller, more manageable chunks by setting an output threshold. If any lines appear when the printing device prints the chunks, you can set an overlap value to produce a seamless image.

On occasion, you may experience difficulties with printing complex files. To print complex files, you may need to spend a considerable amount of time fixing and correcting the files. Another option is to convert a page to a bitmap, also known as rasterizing, which can allow you to print complex files more easily.

To reduce file size, you can downsample bitmaps. Because bitmaps are made up of pixels, when you downsample a bitmap, the number of pixels per line decreases, which decreases the file size.

To specify driver compatibility settings

Back to Top
1 Click Tools Options Global.
2 Click Printing, and then click Driver compatibility.
3 Choose a non-PostScript printing device from the Printer list box.
4 Enable any of the check boxes that correspond to the settings that you want to specify.

To choose a threshold and chunk overlap

Back to Top
1 Click Tools Options Global.
2 Click Printing.
3 In the Special settings area, choose values from the following list boxes:
Bitmap output threshold (K)
Bitmap chunk overlap

To print as a bitmap

Back to Top
1 Click File Print.
2 On the General tab, enable the Print as bitmap check box, and type a number in the dpi box to set the resolution.

To downsample bitmaps

Back to Top
1 Click File Print.
2 Click the Prepress tab.
3 In the Bitmap downsampling area, enable any of the following check boxes and type a value in the corresponding box:
Color and grayscale
Monochrome

*

Downsampling bitmaps affects them only when their resolution is higher than the resolution specified in the Bitmap downsampling area.
