Benefits of the Direct-Indirect Method

Direct-indirect film

The direct-indirect method is a method of creating pre-sensitized aluminum plates using a “direct-indirect film,” in which a photosensitive material is coated in advance over a PET film with a designated thickness.

The following benefits of the direct-indirect method can be raised:

  • Simplification of processes
  • Suppression of uneven film thickness within and between plates
  • Ease of obtaining a flat and smooth surface
  • Improved straightness of printed objects
Photosensitive material layer 12 to 150μm
PET Film 75μm

How to use the direct-indirect film

  1. ① Apply the bonding emulsion from the print surface
  2. ② Apply the bonding emulsion from the squeegee surface
  3. ③ Paste using a bucket while holding the edge of the film
  4. ④ Scrape off the bonding emulsion that has been extruded to the squeegee surface
  5. ⑤ Dry (the time varies depending on the mesh or the thickness of the film used, but approximately 15 to 30 minutes)
