UV-curing varnish in white, black or other colors is used for legendprint (also known as placement printing or service printing).
As a rule, only white varnish is used in the inkjet process. Always ensure that there is sufficient contrast with the colour of the solder resist.

Due to the risk of problems during the electrical test and later during assembly and soldering, care must be taken to ensure that no solder pads are overprinted with varnish.

By default, the position print is clipped with a gap around the solder pads (“clipping”). When placing the labels, it is essential to ensure that they remain legible after clipping.

Even or precisely because legendprint is no longer a significant cost factor in most productions today, or in many cases is offered at no additional cost, the technical specifications are important and should be observed.

Less is often more when it comes to legendprint. It is advisable to only print information, logos and notices that are actually required. Ask yourself whether the individual component contours and designators are really necessary. These are usually no longer required in the assembly process if pick-and-place data is available.
