printed with UV. Please do not write or mark on the positive in the clear areas of the film.
- If your film positive is not to your exact press sheet, we can not make a screen prior to the time of receiving
your printed press sheets. If you provide a full sheet DYLUX (or some other proof ) it must be to the exact press
sheet position in order for us to make a screen prior to receiving production run of your job.

- Minimum sheet size: 12-1/2 x 19
- Gripper margin: 3/4" (minimum to UV area)
- Tail, guide, and wild : 1/2" (minimum to UV area)

| Registration: |
- Please mark clearly guide and gripper, use operator side guide if possible.
- Trapping screen printed UV image to an offset printed graphic image is difficult.
+- a 1/32" is realistic but is dependant on the quality of your registration and paper used.
|
|
| For Both Flood and Spot UV: |
|
| Paper: |
- Full coated sheet of paper (UV is a liquid and "soaks" into sheet).
- NO Matte, or any Uncoated sheets. (Finch fine is uncoated)
- 80# book weight minimum (some lighter weights, with up charges, can be done).
- A #3 or better grade is recommended.
|
|
| Ink: |
- Conventional printing inks should not be used.
- Use of wax free ink(s) and (or) coatable sizing is a must.
- For Flood UV use a minimum of offset spray powder; excess spray powder may not be able to be crushed prior to the UV application. The UV coating will bond to the excess spray powder creating a sandpaper / raised speckled effect.
- For a quality job, Spot UV requires the complete removal of all spray powder from the sheets; any powder on the sheets provided by you will cause a raised speckled effect under the UV coated areas.
|
|
| Drying: |
- 24 hours (fully cured ink) should be allowed before we apply UV coating.
- 24 hours should be allowed after we coat before banding for shipment or
coating of back side of sheet.
- Special arrangements can be made for quicker turn around - however SLC can not be held responsible
any blocking of sheets that occurs.
