In this topic you will find quick tips and links to useful information on avoiding potential PostScript file issues, transparency issues, information on using ONYX PostScript RIP options, as well as guidelines for creating PDF files for wide-format printing.
Because of the many ways elements can be combined in the creation applications, a PostScript RIP file can handle the instructions provided in a PDF or EPS file in many different ways. To avoid potential PostScript file issues, we recommend the following:
NOTE: Converting to EPS may also cause problems with some elements that are not supported in EPS. Be very careful with this workflow.
NOTE: Overprint workflow should be used without color management enabled (all profiles off). Color management can change the mix of inks used thus changing overprint functionality. TIP: To learn more about overprint, see this Max-imize article
The ONYX PostScript RIP engine is incredibly powerful. To simplify your use of the PostScript RIP capabilities, we would like to highlight the following workflow options: SPOTRENDERINTENT- Use this option if you want to change the rendering intent used for out of gamut spot colors (0 = Perceptual, 1 = Absolute, 2 = Relative, 3 = Saturation, and 4 = Postercolor) BLACKOVERPRINT- This option allows you to use overprint instead of knockout for only black elements. BANDHOME - Change the temporary swap workspace of the RIP. This may increase performance as it can move some processing to a separate hard drive. OVERPRINT- This option overprints all channels instead of applying a knockout function when combining separation. USEPDFCROP - This option tells the RIP to use the PDF Crop box from within the image. USECUTSPLINES - This will turn off the splines function for cutters. Use this if you are seeing stray lines in your cut data. These and other PostScript Options will help you get the output you are expecting. To learn more, click here.
PDF Files are complex and issues can appear during printing that are not visible in digital format. To help you avoid potential issues, we have put together simple guidelines for creating a PDF-file that is compatible with large-format printing:
