Poor Print Quality from Adobe Acrobat on 600 DPI Printer

• Microsoft Windows NT Server versions 3.51, 4.0
• Microsoft Windows NT Workstation versions 3.51, 4.0

SYMPTOMS

Certain graphics printed from Adobe Acrobat appear light when printed to a 600 dpi laser printer. When the same graphic is printed on a 300 dpi printer, the printout is darker.

CAUSE

The application is drawing 1 pixel wide lines so, at 600 dpi, diagonal lines appear very light because laser printers cannot hold a single isolated dot on the drum. This is also because of the application not specifying a logical pen width.

RESOLUTION

To print the graphic correctly, you can use one of the following workarounds:

• Change the resolution to 300 dpi.



• Print your graphic using a PostScript printer driver.



• Change the line width in the application.

STATUS

Microsoft has confirmed this to be a problem in Windows NT versions 3.51 and 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
