some typical types for various inks

Toners and Printing Inks- Carbon blacks are very important printing inks. They significantly enhance formulations and offer broad flexibility in terms of specific color requirements. Applications of carbon Blacks include letterpress. Lithographic, gravure, flexographic, and screen printing processes. It is important here to know that each of these processes needs different performance attributes.

JY-140P carbon black is a kind of regular color gas black, it has low ash content, small surface area, low BDP absorption value. Recommend use it in gravure ink.
Type; JY-140P

Particle size (nm ) : 25

Surface area (m2/g ) : 118

DBP absorption (cc/100g): 85

Tint strength (%): 115

PH value: 4.2

Heating loss (%): 2.0

Volatile (%): 6.0

Ash  (%): 0.002

Note: has good performance in water-based inks and coatings.

Offset printing- A high color strength along with high pigment loadings, smooth flow, and a viscosity that is fairly working are needed from the application of Carbon Black. Offset ink must not be miscible with water. If the requirement is high gloss then lower oil absorption pigments are required.

2  JY-6237P carbon black has very good performance in offset printing ink. Becasue it has the lowest absorption value, which can endow it good fludity . At the same time , it's strongh tinting strength can also give it good blackness. This product is a hot saled item in my company.

Type; JY-6237P

Particle size (nm ) : 26

Surface area (m2/g ) : 96

DBP absorption (cc/100g): 43

Tint strength (%): 110

PH value: 7.0

Heating loss (%): 1.5

Volatile (%): 1.0

Ash  (%): 1.0

Note: equivalent to Printex 35. Show good fluidity and gloss when used in offset printing ink. Performance and Feature: Coarse particles, low structure, low viscosity pigment, applied in high-quality offset printing, letterpress printing inks, thermal fixing ink, news ink, gravure Printing

 

Flexography ink- This ink is fluid, with instant drying features. Rheology is a vital factor here. Carbon Black pigments with low oil adsorption pigments are a must.

Pigment carbon black JY-4219P,JY-4230P,JY-420P all suitable for this kind of flexo inks.

Type; JY-420P

Particle size (nm ) : 22

Surface area (m2/g ) : 128

DBP absorption (cc/100g): 65

Tint strength (%): 130

PH value: 7.5

Heating loss (%): 1.5

Volatile (%): 1.0

Ash  (%): 1.0

 

Type; JY-4230P

Particle size (nm ) : 27

Surface area (m2/g ) : 83

DBP absorption (cc/100g): 105

Tint strength (%): 108

PH value: 7.0

Heating loss (%): 1.5

Volatile (%): 1.0

Ash  (%): 1.0

Note: equivalent to Cabot M460

Screen Printing- The critical performance factors are rheology, low viscosity. This can be achieved by pigment blacks that has higher structures. Optical density property can be obtained by relatively low pigment black loadings.

 3 Pigment carbon black JY-4219P carbon black , it can disperse very well in water base system, so we mainly recomend this type in sreening ink.

Type; JY-4219P

Particle size (nm ) : 27

Surface area (m2/g ) : 87

DBP absorption (cc/100g): 72

Tint strength (%): 110

PH value: 7.5

Heating loss (%): 1.5

Volatile (%): 1.0

Ash  (%): 1.0

Note: has good performance in water-based inks and coatings. It’s a very economic grade for black masterbatch. Equivalent to Cabot M430.
