Claims
- 1. A support material for making color test prints in the analog proof system, comprising a paper support having a basis weight of between about 80-250 g/m.sup.2. and a layer thereon comprising a binder or binder mixture which is hydrophobic and a pigment mixture containing hollow micro-balls having a diameter of 0.4 to 1 .mu.m, said layer being receptive to color test printing directly on said micro-ball containing layer to produce images of reduced optical dot gain.
- 2. A support material according to claim 1, wherein the hydrophobic binder is selected from the group consisting of acrylic acid ester, vinylacetate, vinylchloride/vinylacetate copolymer, polystyrene, polyurethane, polyvinylchloride, polyvinylidenechloride, styrene/butadiene copolymer and styrenated acrylic acid ester.

- 5. A support material according to claim 4, wherein said binder content is about 20 to 80% by weight.
- 6. A support material to claim 5, wherein said binder content is about 20 to 50% by weight.
- 7. A support material according to claim 1, wherein the pigment mixture containing hollow micro-balls includes a pigment selected from the group consisting of TiO.sub.2, CaCO.sub.3, ZnO, ZnS, ZnSO.sub.4, Sb.sub.2 O.sub.3, CaSO.sub.4, BaSO.sub.4, kaolin, talcum and mixtures thereof.
- 8. A support material according to claim 7, wherein the TiO.sub.2 content in the pigment mixture is about 10 to 80% by weight.
- 9. A support material according to claim 8, wherein said TiO.sub.2 content is about 30 to 70% by weight.
- 10. A support material according to claim 1, wherein the content of the micro-balls in the pigment mixture is about 10 to 80% by weight.
- 11. A support material according to claim 10, wherein said content of micro-balls is about 30 to 70% by weight.
- 12. A support material according to claim 1, wherein the pigment content of the layer is about 5 to 85% by weight.
- 13. A support material according to claim 12, wherein said pigment content is about 50 to 80% by weight.
- 14. An analog proof system printing material comprising
- a support;
- a layer on the support comprising a binder or binder mixture which is hydrophobic and a pigment mixture containing hollow micro-balls; and
- a light sensitive color test printing layer laminated directly on said micro-ball containing layer.
- 15. A material according to claim 14, wherein said hollow micro-balls have a diameter of 0.4 to 1 .mu.m.
- 16. A material according to claim 14, wherein the hydrophobic binder is selected from the group consisting of acrylic acid ester, vinylacetate, vinylchloride/vinylacetate copolymer, polystyrene, polyurethane, polyvinylchloride, polyvinylidenechloride, styrene/butadiene copolymer and styrenated acrylic acid ester.
- 17. A material according to claim 14, wherein the hollow micro-balls are polymer micro-balls of styrene/acrylate copolymer.
- 18. A material according to claim 14, wherein the binder content of the layer is about 15 to 95% by weight.
- 19. A material according to claim 18, wherein said binder content is about 20 to 80% by weight.
- 20. A material according to claim 19, wherein said binder content is about 20 to 50% by weight.
- 21. A material according to claim 14, wherein the pigment mixture containing hollow micro-balls includes a pigment selected form the group consisting of TiO.sub.2, CaCO.sub.3, ZnO, ZnS, ZnSO.sub.4, Sb.sub.2 O.sub.3, CaSO.sub.4, BaSO.sub.4, kaolin, talcum and mixtures thereof.
- 22. A material according to claim 21, wherein the TiO.sub.2 content in the pigment mixture is about 10 to 80% by weight.
- 23. A material according to claim 22, wherein said TiO.sub.2 content is about 30 to 70% by weight.
- 24. A material according to claim 14, wherein the content of the micro-balls in the pigment mixture is about 10 to 80% by weight.
- 25. A material according to claim 24, wherein said content of micro-balls is about 30 to 70% by weight.
- 26. A material according to claim 14, wherein the pigment content of the layer is about 5 to 85% by weight.
- 27. A material according to claim 26 wherein said pigment content is about 50 to 80% by weight.
- 28. The support material according to claim 14, wherein said support comprises a paper having a basis weight of between about 80-250 g/m.sup.2.
