Photocure Blue is a dual-cure emulsion designed for both textile and graphic printers. Photocure Blue is Blue in color It has a solids content of 41% with 4500 CPS for excellent print definition. Photocure Blue is easy to reclaim and its pot life sensitized is 1-year. Once Photocure Blue is coated its screen life is 6 month under yellow safelights at room temperature. 

Applications;

Photocure Blue was developed for textile printers. 

Data Facts:

Blue in color, this dual-cure emulsion offers 41% sensitized solids and 4500 CPS sensitized viscosity. Excellent for plastisol and water-based inks.  Once sensitized Photocure Blue emulsion should last 1-year. Photocure Blue will work well with mesh counts above 74 or higher.

Exposure Time Reference:

When using a 5-KW Metal Halide Exposure lamp on mesh counts from 80 to 110 as a guide set your exposure time between 110-130 seconds. On mesh counts of 200 to 300 allow 75 to 120 seconds exposure, and for mesh counts of 350 or more allow 50 to 65 seconds for exposure. Remenber, these exposure settings should only be used as a guide since exposure time will vary depending on equipment used, lamp life, type of emulsion, and applied coatings.

Coating Sequence:

It is not recommended to finish the last coating on the print side of the screen.  Finish the last coating on the squeege side. If the coating ends on the print side, the E.O.M. thickness will decrease and go thinner on the print side.  This will cause premature stencil breakdown and poor ink deposit.

Resolution and Hardness:

Some printers do underexpose the screen to have details of images resolved on the screen.  Unless the number of printing impressions is very low, underexposed screens with poor hardness will cause many problems in the printing process, such as premature breakdown, more fish eyes, and pinholes, locking up emulsions with inks, ink cleaners, or other chemicals. It is important therefore, to locate and standardize a proper exposure time and a good hardness scale by mesh count and coating profiles.
