Across
- 3. The variation in thickness within one plate, usually expressed in mils
- 6. A face exposure procedure which temporarily covers portions of a negative prone to fill-in or shoulder broadening during long exposures
- 8. Exposure of a photopolymer with ultraviolet light through a photographic negative to create an image. The clear areas of the negative allow light to pass through, curing the photopolymer. The black, opaque areas of the negative screen the light and the photopolymer under these areas remains unchanged and can be washed away
- 12. Distortion of the surface of image characters on a printing plate into a cup shape
- 13. A photopolymer plate with a thin (2-7 mil) top layer of a photopolymer material, added to improve image fidelity at the printing surface
- 14. A thin (less than I mil) protective coating applied by the plate manufacturer to the surface of sheet photopolymer plates.
- 15. A removable cylinder covering on which plates are mounted
Down
- 1. Term to describe the hardness of the plate
- 2. A thin (5 mil to 10 mil), dimensionally stable material adhered to the back of most photopolymer plates.
- 4. The ability of a material to rebound, or bounce back after being impacted.
- 5. Exposure of a photopolymer with ultraviolet light, usually through a transparent polyester backing sheet, to create the plate floor:
- 7. The amount of photopolymer material washed away in a set period of time, usually expressed in mils/minute.
- 9. A polymer material which is sensitive to ultraviolet light
- 10. The raised image on a flexographic printing plate.
- 11. A measure of distance equal to 1/1000 of an inch
