Inkcups Now’s Cobalt 1000 laser etching machine is a serious piece of machinery. It is important to understand what this machine can do and if you are ready to own one before you make a purchase. Follow these three easy steps to better understand if you will benefit from a Cobalt 1000.

The first step is to evaluate your business. Is volume increasing? Are orders becoming overwhelming? The Cobalt 1000 etches faster than any other laser we offer because of its powerful ND YAG laser technology. Co2 lasers are weaker than YAG and require more passes over the plate or part, taking up to 10 times as long to make an etch.

Do you require a higher quality image? The spot size for the Cobalt 1000 laser etcher is significantly smaller than Co2 lasers, by about 10% or more! The smaller dot size results in a finer etch, ideal for small text or a high quality print.

The second step is to evaluate how this machine will grow your business. There is no question that the Cobalt 1000 will give you higher quality etches, however it is up to you to determine how you will use it to your advantage. If you are currently using a laser engraver, photopolymer plates, or want to start etching, the Cobalt 1000 will increase production speed and quality.

The third step is to contact an expert. Do not act out of instinct or by internet research, talk to an expert that can provide you will all the information you will need to know. Talk to the Inkcups Now laser experts who build and install these machines!


The Effects of UV Light on Photopolymer Plates

Photopolymer plates work hard to hold ink for pad printing machines. However before the plates get to that point, they need a little rest and relaxation. How do photopolymer printing plates relax? They go tanning.

Photopolymer plates like to get a nice tan. They enjoy spending time in their UV tanning beds (exposure units) until they achieve the perfect tan. If the printing plates are taken out of the exposure units too early they will not do their job properly. The plates will hold too much ink, resulting in too much ink pick up on the pad. The image will come out bold and poorly defined.

On the other side of things, if our friends are left in the exposure unit too long, they will come out tired. The plates will be too weak to hold the proper amounts of ink. The plates will be shallow resulting in not enough ink pressed down on the part.

The best solution for too much or too little ink pick up is to keep your polymer plates happy. Treat them with care. Keep a close eye on them and time the exposure. Give them a great tan and they will give you great prints.
