Print File Common Mistakes

Incorrectly or poorly prepared print files can break a print. We've addressed some of the most common (and often easy to make) print file mistakes and how to fix them. Resolving these issues before sending the artwork to us will help maintain lead times.

Low Image Resolution

Low quality / small size raster files are without a doubt the most common print file mistakes we come across (although this doesn’t apply to vectors, as they can be scaled non-destructively).

How to Fix: Ensure you are working with the high resolution file.

Artwork for print should always be:

  1. The dimensions you want it printed
  2. At least 300dpi
Example of Photoshop Dimensions and Resolution Setup

To print a design 27cm x 35cm, it should look like this in Photoshop at the creation stage.

This should be done at the beginning of the artwork creation process – if you try to scale up an existing raster file, the quality will have already been lost.

Note: Also be careful where you upload/download your image files from. Sites like Facebook will compress your images, resulting in a loss of quality. It’s best to email the original artwork directly to us, or using a website like WeTransfer. See our page on sending large files for more info.

Broken Fonts

This will happen when supplying artwork where the text has not yet been either outlined (vectors) or rasterized (raster art). The text tries to re-access the font, because it thinks it is installed on the computer. If it doesn’t exist on our computer, it breaks the link and the software has to substitute it.

The examples below are the same file – the first image did not have the text outlined.

Font that hasn't been correctly outlined

Font incorrectly prepared. This is how we see it.

Font that has been correctly outlined

This is the same font, but correctly outlined.


Text Typos

The easiest of print file mistakes to make, and a potentially expensive one to fix if not caught before production. We always try to watch out for spelling and raise it if we have any doubts. However, naturally customers quite often present us with intentional, unfamiliar spelling variations or made-up words (such as brand names, etc). Therefore, we cannot always reliably flag these, as to us they often appear intentional.

How To Fix: We cannot stress enough how important it is for you to check all spelling.

Poor Quality Scans

If you’re looking to screen print a drawing you’ve created on paper and aren’t intending to modify it digital, it’s still important to make sure the file is correctly prepared. Due to the nature of scanned art, we will assume that we are printing everything exactly as supplied. We aren’t in a position to know what is intentional/unintentional, so we will also assume this for stray marks, smudges, hand written text, etc.

How to Fix: It’s important to ‘touch up’ your scanned artwork before sending it to us. Things to watch for include: stray marks (from pencils, rubber usage), smudges, wonky / blurry text and dirt/dust from scanner. You should make sure that the background around the design is completely white (#FFFFFF) or transparent. Any slightly off-white background areas that are left in the artwork, could distort the artwork or even potentially carry over to the final print.

Halftones That Are Too Fine

If you provide your artwork with your own halftones incorporated, it’s important that the halftone is suitable for printing. There are two ways a halftone can end up too fine – either the halftone is created too small to start with, or a halftone is applied to an image that is too big. If an image is too big and requires scaling down to print size, then the halftone details will become smaller/finer. This is another reason to make sure you create artwork at the size you would like it printed, before applying the halftone.

How To Fix: Generally, we recommend providing a copy of your artwork before applying the halftone and another copy after applying it. This way we can see how it should look, but gives us an opportunity to adjust the halftone if we think it needs modifying.

Halftone dots showing high LPI frequency

A halftone too fine or reduced by scaling may fill in.

Halftone dots showing a lower LPI frequency and larger dots

Lower dot frequency reduces unexpected results.

Altering Artwork On Your Behalf

We prefer art to be ready in advance, however we can make minor changes and fix some print file mistakes on your behalf. We generally charge for this at a fee of £30/hour, starting at £15.

Changes We Can Make

  • Simple colour changes or removal
  • Rearranging supplied logos
  • Simple colour changes
  • Resolving certain print file mistakes (upscaling and others on this page)

If supplying logos, you must make sure they are all of a usable quality for print.

We do not charge for separating artwork for print, nor do we advise you trying to separate it for us in preparation. This tends to just add complications and increase turnaround time. Saving the artwork as a complete piece (layers are fine and sometimes useful) at the size you require it printed, is generally all we need. Supplying a mockup for us to use as a visual guide can be helpful too.

If you’d like us to look at your artwork to see if it is suitable for printing, feel free to email it over and we will happily check it for you. You may need to use a site like WeTransfer if they are large file sizes.
