Wholesale Flint High Quality Water Nylon Resin Washable Polymer Pad Printing Plate

Quick Details


Use: Pad printing
Material: Aluminum
Style: Positive
Type: PS Plate
Application: Pad printing

Remove the raw plate from its packaging, cut it to the required size with guillotine shears, place it on the vacuum plate of an exposure unit with the sensitised side upward and remove the protective foil.Depending on the printing (direct or indirect), place the non-reversed or reversed image positive film, matt face down, onto the plate, roll the vacuum foil over film and plate and activate the vacuum. If necessary, use a soft anti-static cloth or a foam squeegee to ease out any trapped air. After quickly checking the vacuum and closing the lid, start the exposure with the set time.

Drying


In the case of nyloprint flowline washers (water) with an integrated dryer (DWT), the plate is already dried and
postexposed when it leaves the unit. The cliché is ready for immediate use.When using a washer from the CW combination or a unit with a similar design, once the plate has been exposed,it must first be rinsed to remove any remaining washout solution (alcohol/water mix or water). The plate is then placed in the dryer and dried for the specified time at the specified temperature.It is important, for water-washable plates, that no residual water remains on the plates, as this could damage the relief layer and the relief adhesion when the plates are heated in the dryer.

Test negative


To determine the optimum exposure time, Printing Plates provides a test negative made up of
various critical elements, to be used to establish the exposure times.The test elements shown are combined in a negative film with 8 copies. A step exposure is performed with these 8 copies.
