Paying specific attention to the images section, the resolution down-sampling can be edited to meet custom specifications. Especially when you consider that jobs can also be bogged down with complex vectors, as well.Īlso shown above is an Enfocus PitStop Action List used to optimize PDF files. But if a client supplied a 500-page PDF file that was already data merged for mailing, it becomes a big deal quickly.
The effective resolution is 400 ppi, which is overkill for this A5 card. This page contains an image that is oversized. And it will presume that each print shop knows what image resolution it requires for plate making or digital output. This article will avoid discussing ppi vs dpi and let that argument lie. This has changed over the years, especially when considering making plates versus digital print. When we got out into the real world, the rule of thumb for image resolution used to be, make the ppi two times the dpi. In training, we were taught that an image had to be 300 ppi at 100% to be printable. However, there are also instances where PDF file sizes are very large due to extra data and images that are of a higher resolution than necessary. Print production teams are often faced with images with resolutions that are too low to reproduce with acceptable quality.
