RIP is short for Raster Imaging Process. This process “translates” the information being sent by the computer into a file format that a printer can recognizes. Pre-press departments should have someone who is trained for trouble-shooting problem files. Most RIP errors/problems are traced back to their original file.

The following are suggestions for you to consider if you are having issues with your RIP:

  • Size Matters – RIP files tend to be big. Before you do anything, make sure your computer is fast enough and big enough to handle large files
  • RAM Memory – Make sure your computer has enough RAM. Your system should have enough RAM to perform the task. If not, it will use the hard drive as an alternative memory source. The constant swapping of data adds extra time to the process and can create possible file errors
  • Healthy Hard Drives – Have lots of hard disk space for these large files. Typically you should have 3-4 times the size of your RIP available on your drive. Keep your drive defragmented by using third party programs and run at least daily
  • Color Correct – To avoid color surprises and confusion, calibrate for accurate consistent color output. Every Media needs to be calibrated for the type of printer and ink used. Some Media come with basic ICC Profiles that need to be fine tuned to your specific situation
  • File Integrity – One of the most common problems is file codes too complex. Raster files tend to get huge as print sizes increase. Vector files can be enlarged endlessly and use Nodes to set line paths. Too many Nodes can cause PostScript problems. Auto-tracing set up with too high a level can create horrendous amounts of Nodes. Trying to clean any or all of these after the fact is difficult at best
  • Masks – Complexity problems can revolve around Masks. Masks are often used by designers in a hurry to hide unwanted details of the image instead of just deleting them. Unused junk is covered by this Mask. However, a RIP does not recognize Masks and having them will extend processing time
  • Color Issues – Most RIP’s use the CMYK mode. Software also has color management features which should be turned off as they can conflict even with careful calibrating. Compression features can also cause problems for RIPs as they attempt to uncompress files while RIPing

All of these above issues are time consuming problems to fix after the fact and can cause weird and unpredictable results. Clean, concise basic file data is always the best way to start. Educating clients and staff about proper file set-up procedures can go a along way towards saving you time, frustration and energy.
