Ceramic color paper paint application considerations

Each flower paper factory application of pigment, mostly use local materials, or from big companies into raw materials, and imports of raw materials.

Me to introduce my two biggest pigment, commonly used in ferro companies in the United States the original German (dirk) and heraeus Germany's pigment precious metals company. For color paper company pigment stability is life.

No matter to test every company paint, paint surface color is the first step, because the paint raw materials, and production conditions change, the color of the surface or deep or shallow, and change, for a record, in the next time you print the basis, the second step proofing barbecue, and can be best 300 mesh proofing to verify, 200 mesh pull test is not very accurate. To test every color, black also want to test, some all for black can pull, the question is not so simple, because of the black also changes of raw materials in the black solvent is more shallow, solvent less deep and 200 mesh is hard to see, we didn't refer to the original sample, printing the captain often sometimes relying on experience to solve, or baked sample to judge color. Black sometimes slightly change, color proofing we play, domestic proofing with artificial color have big discrepancy, we call generally 10 to 20 grams, the less the proportions of the black inside again change. When the production machine we can show slight change black to pull, so we should estimate of pigment, oil ratio on the adjustment again. Our company headquarters in large machine proofing, color is relatively accurate, there would be no big changes.
