Standard Anilox Roller Engraving Specifications

In narrow web flexographic printing today with machines capable of such fast speeds; concentricity and consistency can be maintained reducing the variables, which allows the printer a greater selection of substrates and ink types for their particular applications. With all these changes, the narrow web printer is still able to perform with a minimal number of Anilox Roll screen counts. The following can be used as a guide to roll selection in the industry today.

Coatings Applications	Chrome*	Ultaflow Ceramic* LPI/BCM/Degree
High volume applications, high viscosity coating	150Q 18.4 x 10^9	100 / 18.4 / 60
General Purpose
Printing kraft and other open pore paper	120Q 21.8 x 10^9	120 / 18.0 / 60
Solid reverses, clean type on paperboard/irregular surfaces	180Q 11.1 x 10^9	180 / 11.0 / 60
General purposes; strong color, clean print; 8 pt. type	200P 6.6 x 10^9	360 / 5.0 / 60
Smooth solids, reverses, 85-100 line screen 6 pt. type	360 3.8 x 10^9	360 / 4.6 / 60
Clean positive type, solids, reverse; 85-100 line halftones	360 3.8 x 10^9	360 / 4.6 / 60
Fine Line, Halftone, Process
Combination printing of screen and type: UPC codes	360 3.8 x 10^9	400 / 4.0 / 60
Fine lines, some reverses; 100-200 line halftones	400 2.8 x 10^9 550 2.6 x 10^9	600 / 2.6 / 60
Process printing, 120-150 line halftones	550 2.6 x 10^9	700 / 2.2 / 60
Fine process printing, 133-150 line halftones	550 2.6 x 10^9	700 / 2.2 / 60
Process printing up to 200 line halftones	N/A	1000 / 1.2 / 60

GENERAL PRINTING 360
Covers day-to-day printing, some fine line, some reverses and solids. Recommended and inventoried by most press manufacturers for the most generous versatility.

FINE PRINTING SCREENS & PROCESS 600
The 600 LPI is most recommended and inventoried by press manufacturers for its versatility in fine screen printing. It can handle a variety of solids with good success. The printer most usually establishes the screen needs based on the equipment and capabilities. Whatever screen count used for the Anilox Roll on these fine engravings, they will usually run a higher than normal viscosity ink and a reverse angle doctor blade. There are applications using up to a 90 Durometer rubber roll.

FLOOD COATING
200 LPI is good for large solids where color is important for total coverage, etc. where a good grade paper is used, also for U.V. coatings. 165 LPI is used for more absorbent papers where detail is not as important. Both screens have had success with U.V. coatings depending upon the shear point of the coating from the manufacturer. Both screens have had success with varnishes.

ADHESIVES
100Q & 85Q where heavy coatings ¾ mil, ½ mil, etc, are necessary in narrow web. These applications are recommended as chrome anilox rollers, guaranteeing a 100% release of solution. And since chrome rollers are half the cost of ceramic, they are easier to expend than a ceramic anilox roller. These screens are capable of throwing the solution out of the pan as well as challenging the drying systems.

U.V. COATINGS
This coating today is applied thru as many different screen counts as ink, from a 200P Screen to a 120P Screen, the factor seems to be the shear point of the solution and not the viscosity. The rule of thumb seems to be if you receive a cockle finish, get more volume from your Anilox Roll.
