If you haven’t read "FULL SPEED AHEAD - How to make variable data PDF files that won't slow your digital press" by Martin Bailey of Global Graphics yet, you should. There are a lot of great tips on how to keep your iJetColor system printing jobs at full speed by making sure that your PDF files are designed effectively. Here are our top 3 tips from the guide:
1. Make sure that your image resolutions are set appropriately
Given the effective resolution of the iJetColor systems – we recommend photos with resolutions no greater than 300 pixels per inch – higher resolutions are virtually never more productive.
2. Don’t flatten transparency
Flattening transparency upstream of the DFE can have two significant unwanted effects:
- It can make the file size much larger by trying to keep the visual appearance exactly the same.
- It can create some imperfections in the output if done without comprehensive knowledge of the press.
3. Optimizing colorDon’t use too many spot colors because it will slow down the processing speed of the DFE. It's not necessary to match a spot color for every different color in a job. Doing so will increase the memory requirements and processing load with the inevitable slow down the speed of the job.
