Flexo printing defects are frustrating and expensive, harming the quality of your printed products and making print jobs look unprofessional. Fortunately, the most common printing defects also have common causes and, in many cases, simple solutions. In this blog post, we look at three of the most common defects you should be aware of.
'Dot gain', sometimes known as tone value increase (TVI), is a flexo printing defect characterised by the diameter of halftone dots increasing during the printing process. Essentially, this means the dots on your printed substrate come out larger than intended and, in many cases, this will result in printed material looking darker or fuzzier. Ultimately, dot gain is a problem because it can have a detrimental impact on the quality of your final printed product. Dot gain is usually expressed as a numerical value, giving the difference between the dot size on the source file and the actual dot size on the final printed product. Fortunately, with flexo printing, there are steps that can be taken to minimise the problem. Let’s take a look.

The printing cylinder is loaded onto the system and double sided adhesive tape applied to its surface.
Increasing the speed of a printing press is a common goal for many printing businesses. After all, the difference between 300 fpm and 600 fpm, when evaluated over the course of a whole year, can make an enormous difference to the number of items that are printed and, consequentially to your profits.
