I am currently working on a print project for one of my clients and I was given a folder of files including images, many of which are in the wrong format. This has made me realize that whomever built these files may be inexperienced as a”designer” and is just using images sent from their clients “as is.”

I’m wondering if the “designer” is lazy and not interested in converting the images or just doesn’t know any better. The reason I’ve put the word “designer” in quotes is because perhaps the person building the InDesign file is just an office worker or someone who learned the InDesign and Photoshop programs, but just doesn’t know what’s correct.

So, my first question is, when the files are sent to the printer, does the printer contact the “designer” and say some of the images are in the wrong format, or is he lazy also, and just prints the document.

If you’re going to print something, a jpg or gif file is the wrong format and probably the wrong resolution as well. One of the reasons people may send jpgs or gifs or even pdfs is because they are perfect for emailing and posting on a website, but they must be converted once received, not only into a print format (cmyk) but the resolution must be correct (300 dpi or higher in some cases).

Below is a little chart to follow just for formatting imagery:
