New imPresstm ID paper additives from Solenis dramatically increase the performance of paper printed on HP Indigo presses.
Solenis Introduces New imPressTM ID Paper Additives for HP Indigo Digital Presses
Designed specifically for HP Indigo digital presses, the new imPressTM ID chemistries are up to eight times more efficient at generating print adhesion
A main benefit is improved runnability. With imPressTM ID additives, no changes are required to the size press or machine settings. The chemistry is non-charged, so it doesn't form deposits, agglomerate or cause stickies-related issues. In addition, the new imPressTM ID products are exceptionally versatile and work well with optical brightening agents and other size press chemistries.
Our researchers spent a great deal of time refining this product, said Dan Varnell, Solenis Research Fellow. The result is an innovative chemistry that dramatically increases the performance of the paper printed on Indigo presses.
In the past, polyethyleneimine (PEI) or poly(ethylene/acrylic acid) was used to promote Indigo image adhesion, but PEI resulted in yellowing issues and P(Et/AA) dispersions required special conditions. The Solenis imPressTM ID technology relies on thermodynamic attraction of the print ink to the paper treatment. Free energy drops as the ink and the treated paper interact with each other, resulting in more efficient adhesion.
Currently, imPressTM ID-115 and ID-120 are available in North America, and imPressTM ID-215 and ID-220 are available in Europe.
