Print-quality issues Some objects are missing from the printed image Large quantities of data may be necessary to print a high-quality large-format print job, and in some specific workflows there may be issues that can lead to some objects missing from the output. Here are some suggestions to help you to avoid this problem. ● Try using the PostScript printer driver to print your job, if you have not already tried it. ● Select a smaller page size and scale to the desired final page size in the driver or in the front panel. ● Save the file in another format, such as TIFF or EPS, and open it with another application. ● Use a RIP to print the file. ● Reduce the resolution of bitmap images in your application software. ● Select a lower print quality in order to reduce the resolution of the printed image. NOTE: If you are working under Mac OS, not all of these options are available. These options are suggested for troubleshooting purposes and may adversely affect the final output quality or the time necessary to generate the print job. Therefore, they should be cancelled if they do not help to solve the problem.
