Essential information for skilled users of photoresist films for sandblasting

Exposure time of photoresist film in exposure unit

We suggest to exposure RAYZIST film SR3000 half time than you are used to the competitive films.

For example: When use an exposure unit with 6 x 20W performance, the time of exposure of the SR3000 film is only 6-8 seconds.


The best way how to washout the RAYZIST film SR3000 is by gun with spray nozzle with water pressure 60–90 psi (4-6 bars), from 5 – 10 cm distance according to detailed artwork.


Dry the stencils according to current room condition, e.g. 20-40 min. 

Application tips

  1. Slightly bend the edge of blue layer side for easier removal of the clear cover film.
  2. If the film does not stick enough, revive stickiness by breathing or light “steam” over water steam.
  3. When apply the stencil, it is appropriate to press the stencil sufficiently with your thumb or burnisher.
  4. You can reposition the stencil repeatedly until you are satisfied with its position.
  5. Use “bubbleEx” to remove air bubbles and break up the microfilm.

What are the different types of photoresist films?


– classic wash out, self-adhesive, photoresist films, which are available in three different thicknesses. Engraving stencils from these films are repositionable and designated for detailed engraving of various glossy materials. Special adhesive Rz-2 can be applied to increase adhesion for sandblasting matt surfaces.

76 μm (3 mil)

– ideal for fine detailed artworks and engraving of halftone photos on materials such as crystal, glass, hard metals, acrylics and plastics

102 μm (4 mil)

– for deeper and deep sandblasting of detailed artworks

127 μm (5 mil)

– for deep sandblasting of less detailed motives into hard materials such as wine bottles


152 μm (6 mil)

– this type of photoresist film is not self-adhesive. After the engraving mask is dried and before its applying is necessary to apply Rz -2 adhesive, which we also supply. After application of the adhesive, it becomes a highly adhesive engraving mask and it can be even used on unpolished stones. Engraving masks made from this film are suitable for very deep engraving of hard materials.

229 μm (9 mil)

– it is an durable sandblasting film for stonemasons, for making lettering and art works for monuments, granite, stones and other very hard materials
