Screen Printing Inks

Everyone in the pad printing and screen printing industry could do with some useful ink tips now and then to freshen up the memory and maybe learn something new! That’s why we want to bring up some common ink issues and how to go about solving them.

• Add a touch of blue to make your white ink brighter

We happen to get calls from customers sometimes asking about how to brighten white screen printing or pad printing ink. To do so you can actually just add a touch of blue color to it. More specifically, #32 from any of our ink series would be the best option.

• How to handle misprints

Removing misprints from plastics is also a issue for some people. The best way to handle it is to use our Ink-Away Remover to clean the substrate and then overprint the shadow before removing the object from the nesting fixture. However, if the ink attacks the plastic it may be impossible to re-claim the item.

Harmony Ink Dispenser

To continue on our subject of tips and guidelines like the posts about printing pads and ceramic rings, we now want to raise awareness about pad and screen printing inks and ink mixing!

There are basically two ways to go about ink mixing; you can either pour the ink by hand or use our Harmony Ink Dispenser. The difference is that with the Dispenser, you have fine control over the amount of ink/thinners you mix (because of calibrated pumps) and ink does not get spilled around (even if your hands are shaking a little after yesterday ). Also the unmixed portions are preserved in Dispenser’s canisters instead of drying out all over the open cans. The ICN 1501 Digital Scale gives you (+/-) 0.01 gram accuracy, needed for precise measurement.

Follow these steps to achieve best possible ink mix:

• • Make sure you use unlined mixing cups (no wax) and wooden or metal mixing sticks! If you use plastic, your ink may get contaminated with plasticizers.
• • Zero the scale out and make sure its on a leveled surface. Read more
  

Ceramic Rings

Are you using a single-sided or double-sided ceramic ring? If you are using a single-sided ring you should look into the benefits of using a double sided instead. The most obvious reason has to do with the fact that rings can get damaged… yes, sooner or later it will happen, but if you have a double-sided ring you can simply flip the ring over and continue pad printing. If you need to re-assemble an ink cup or flip a double sided ceramic ring but not quite sure of how to do it, we have a video with easy-to-follow step-by-step instructions. Go ahead, check out our Ink Cup Assembly - Ceramic Ring Changeover video

Worn Out Pads

Have you ever experienced problems while pad printing such as repeated misprints or voided prints? If so, your initial reaction was most likely that it was caused by the ink. However, many times it is due to the fact that the printing pad needs replacing. If your pad looks anything like those on the picture, it’s about time you get a new one!

By the way, for a limited time, we have a Buy 5 Pads Get 1 Free offer for you. Search our pad selection and call in for more details at 978-646-8981.

Common Issues Caused by Old Pad

• • All silicone pads have oil in them to pick up and transfer ink properly. If the pad dries out you may experience voids in the prints.
• • If the image is burnt into the pad that means it has dried out. This can be caused by using a high ratio of hardeners or thinners in your ink - hardeners and some thinners are aggressive to the silicone surface. This is normal and doesn’t necessarily mean that there is something wrong with your ink mix - but you will have to change your pad more often. (The life of the pad also depends on what substrates you print on, for instance, softer plastic materials is gentler to print on then hard metal objects.)
• • Pads can also get saturated with thinners, leading to poor ink pick-up. If the saturation happens, the pad will dry out quicker than it should.
• • When the pad durometer changes (due to dryness) softer pads get softer and harder pads get harder, which will also affect the outcome of the artwork.

We’ve seen a lot pads and done a lot of pad printing here at Inkcups. Our conclusion is: if you are continuing to use a deteriorated pad instead of getting a new one, you are wasting much more than you are saving because of all the misprints and aggravation.

How to Take Care of Your Printing Pad

Even the best pads won’t last forever. However, you can prolong their life by regular maintenance.
