Silk screen printing ink color

5) viewing conditions: color should be observed in standard light observed inside the photometer measured by spectral color spectral curves are more conducive to the standardization of colors.

6) adjust the amount of ink: spot color ink formulation too much, causing the remainder of the waste, if less is not enough, also need to deploy again, complex color second color ink is difficult to reconcile with the first deployment of exactly the same color, for Printing quality have influence, it should be slightly more than the actual amount of ink formulations, and the amount of the actual printing area is mainly composed of print and ink film thickness to decide.

3, Color Illustration:

1), the three primary colors of light: the three primary colors is the essence of the independence of the three primary colors, primary colors in the same color not use any remaining two color synthesis. In addition, the three primary colors mixed with maximum gamut, other colors by mixing primary colors out by a certain percentage, and the largest number of mixed color obtained.

From pigment mixing experiments, it was found that energy spectrum of wide range of wavelengths colorant cyan, magenta, and yellow through (or transmit), can match more colors. In this experiment, based on the people to further clarify: There are cyan, magenta, and yellow pigment mixed in different proportions to obtain the maximum color gamut, while the three pigment itself, can not use a mixture of the two remaining pigment. Therefore, we call cyan, magenta, and yellow pigment primary colors slightly.

Screen technical knowledge

1, the network version of the production process:

2, screen selection technology:

Since the scope of screen printing is very extensive, so the relevant factors in this are multi-faceted, in the selection screen,

To choose a different screen depending on the circumstances and printing requirements.

1), depending on the type of substrate selection screen:

a, fabric printing: You can use thin tulle, nylon or polyester mesh screen.

b, sheet printing: optional thin tulle, thick tulle, nylon mesh, thin polyester mesh, multifilament polyester mesh, monofilament polyester mesh.

c, plastics, glass, ceramics, metal products, wood products, printing: the choice of thick tulle, monofilament nylon mesh, thin polyester mesh, thin tulle, stainless steel mesh.

d, Electronic Components Printing: You can use thick tulle, monofilament nylon mesh, multifilament polyester mesh or metal mesh.

2), according to the ink properties selection screen:

Different inks have different printability, so when the screen you want to consider the ink drying time and color sharpness, ink absorbing substrates and other factors selection screen.

3), according to the choice of the screen mesh material and performance:

The physical properties of the material and the screen itself, whether printed adapted to the conditions, which the appropriate choice of screen types.

4), according to the printing selection screen shown:

To consider the printing speed, printing pressure, printing anti-Indian forces, substrate absorption capacity and other factors choose the selection screen.

3, the choice of screen Notes:

1), the degree of difficulty through the screen of:

Ease of ink through the mesh network is considered the general election is more problems. Halftone ink and transparent inks, whose pigment particles finer, this ink can use high-mesh screen. Inks, the high concentration of pigment inks for special purposes, you can use low-mesh screen.

2), the substrate surface

If the substrate surface roughness, generally use a lower mesh screen.

3), the fine level:

According to the original level selection screen graphic fine lines, printing fine lines to select high mesh screen.

4), screen quality:

When you select a screen, you should also check the screen quality, such as silk warp thickness ranging from rough surface is not smooth, uneven.

5), screen costs:

In the meet the printing requirements of the premise, try to use less expensive screen.

Screen technical knowledge

4, screen save:

a, heat: when common screen nylon mesh, polyester mesh, tulle, the expansion will happen after these mesh heat, leaving the wire diameter aperture ratio and mechanical properties change, to save space should maintain the proper temperature . Polyester-based mesh should also pay attention to store fire, avoid screen burn or screen local heating.

b, anti-stress, anti-collision: the weight and impact, will screen the aperture ratio changes, causing severe fracture mesh network path.

c, Dust: If wire mesh attached to the dust, traces of oil, will directly affect the quality of the plate, so when stored, should pay attention to dust, and avoid sticking oil. After use, it is best placed in a plastic bag or wooden box.

The main characteristic index screen printing mesh material commonly used:

Common screen printing screen has tulle, nylon mesh, polyester mesh, stainless steel mesh. The main characteristics of various screen indicators are the following aspects.
