Good news! Two new Jet plates available: LSM 94SM and LSL 43SM

LSL 43SM LSM 94SM new jet plates

Anyone visiting our website over the last few months has noticed that we are currently out of the Jet LSL 73SP plates we normally carry and recommend for use in making photopolymer gravure and intaglio plates. The pandemic has been a challenge for supply lines over the entire planet, and one of the key components of these plates is temporarily unavailable.

We don't want to leave printmakers without any options, so we have now tested two similar plates from Jet USA, the LSM 94SM and the LSL 43SM. We are happy to report that these plates are very suitable for photopolymer gravure and other photopolymer intaglio methods.

The key differences are as follows:

  1. The LSM 94SM plate is slightly thicker. The LSM 94SM is 0.94mm (0.037") thick versus 0.73mm (0.029") for the LSL 73SP. The LSL 43SM plate, on the other hand, is thinner than our original plate and measures 0.43mm.
  2. The finish on both plates is a matte finish instead of glossy. This means that wiping is slightly different, but is easily done. It behaves more like copper in the way it grips ink and how it is wiped. The super-soft wiping fabric we sell makes the final wipe of these plates very easy and controllable.
  3. The exposure time for the LSM 94SM plate when using direct-to-plate technique is the same as the LSL 73SP plates.
  4. The exposure time for the LSL 43SM plate when using direct-to-plate technique is shorter than the LSL 73SP plates. Our testing shows it to be 2 stops faster, e.g. 2 minutes instead of 8 using our UV-LED light source.
  5. For those doing direct-to-plate methods, the plate will require a slightly higher ink load of matte black ink. The QTR maximum mK ink load that works well seems to be around 40%.

Since we don't know when we will get more of the LSL 73SP plate material, we will have a large stock of the LSM 94SM and the LSL 43SM material for sale so our customers can continue to make plates.
