A press check is a service offered by print companies allowing you to come to a review your print project once it is on press. The pressman will get everything setup and print a few sheets for you to review before hitting the go button on the entire project. This step is important for various reasons to ensure your print project comes out exactly how you want it. Below are a few important things to look for during your press check.

1 – Low Resolution Images

Images used for marketing are often pulled from online sources or images taken with a phone, these images can and most likely will print at a low resolution, meaning that once printed on a substrate, they can become pixelated or blurry. The standard print resolution for a print file is 300 dpi, many images online or from your phone can be only half of that or less, making them impossible to print at a larger scale than what shows on your phone or computer screen. When reviewing your project at a press check, this will give you a proper representation of the print quality for those images.

2 – Ink Registration

Most offset printing is done in CMYK, a process of 4 colors printed in layers to create a specific color image or text. If these colors are not in registration, you will be left with a blurry and hard to read piece. It is important to make sure there is perfect registration. Pressman will have a tool called a loop at their press; this tool allows you to magnify the print allowing you to see the registration. If these colors are off the pressman can adjust to get them realigned.

3 – Color consistency

This is the process to which the colors are consistent across the entire sheet. Color management profiles are used to ensure color consistency throughout the printing process. Review your press sheet thoroughly and make sure the entire sheet is equally vibrant without any dull areas. If there are any issues with consistency, your pressman and prepress department can review and adjust the print management system.

4 – FPO

FPO means FOR POSITION ONLY, when creating your digital print file, you may use an FPO for things such as die lines, foil stamps, scoring, punching or folds. These are important during the prepress process so we know how your art should be laid out to avoid any of the processes listed above from impeding into your final print piece (nothing is worse than trying to read text that is on a fold.) Most of the time these FPO are created in a bright pink, but not always. It is important to make sure your FPO has been removed from the press ready files, so your FPO is not printed in your final piece. FPO should be created as a separate layer in your file so it can be turned off when plates are made for printing.

5 – Check Your Mailing Panel

Mailing panels are tricky, USPS has a lot of rules for mailing panels, such as size, position and the ability to inkjet. If your print piece has a coating such as Aqueous, UV, Soft Touch or any other coating, be sure the pressman has created what is called a knockout, this is a process where they keep the coating from being applied in the mailing panel area. If that area is coated, USPS will most likely reject your pieces causing you to reprint.

6 – Pagination

If you are printing a booklet, with multiple pages on a press sheet, it is important to fold that press sheet to make sure your pages line up properly when folded and stitched. The prepress department has programs that will assist with correct pagination, but it’s always at idea to manually check this for accuracy. Also keep an eye out for alignment, making sure your page numbers land in the same place when the sheet is folded on the crop marks, and there is no art in or around the spine. One last thing to look for, make sure the creep has been accounted for. When you have a large book that has multiple sigs, when those sigs are folded and nested together the outer most sigs will need to be adjusted so the art has more room on the spine, or the inner most pages are not pushed out too far that they get cut off when the final trim is made.
