In this video, we show a very simple pre-flight scenario. In printing, pre-flight is the process of confirming that digital files are valid, correctly formatted, and of the desired type for high quality results. If you are interested in making sure your postcards are set up properly for us to print quickly, be sure to watch this video.
1. We only accept PDF, JPG, TIFF, PNG, EPS, AI
2. Resolution should be at least 300 dpi. In this video, the customer selected to use 350, which we preserve.
3. We flatten all images. Sometimes transparent layers can cause issues. We ask clients to flatten all layers.
4. We convert to CMYK color mode for everything 13×19 and under. We do use a SWOP color profile as well. This customer turned in an RGB file which is better suited for digital screens
5. We check for bleed and trim area. This file was sent to us as a 4×6, but it really should have been 4.25×6.25 so that we have room to cut and produce a “full bleed” or edge-to-edge final print. In this particular case, we were easily able to fix the problem.
6. We save everything into a production quality PDF using presets that we’ve perfected to properly serve our equipment. Much of the complex pre-flight happens there.
Most of the pre-flight on our side happens though our automated presets, but every file is checked for color mode, file type, existing layers and suitable bleed area by an actual human being. We do our best to fix issues before asking customers for help.
