Question about an ink trouble

Please let me know the kind of aluminum paste.

It is divided into aluminum paste by the difference in a surface treatment at three kinds.

  1. Leafing type
    In order to float in the surface, it will oxidize, if air is touched, and although there is luminosity, if metallic luster falls or it rubs by hand, aluminum will be attached to a hand.
  2. Non-Leafing type
    Although it does not float in the surface, exfoliation between layers may be caused with an ink type.
  3. Resin coating type

    Although it is what carried out coating of the aluminum surface by the acrylic resin etc. and adhesion nature improves, luminosity falls. 

    In addition, I am also preparing the special aluminum out of which gloss comes like a mirror.

Although it is gelling when PP ink and OP22 ink are seen in a winter season ...

PP system ink will be gelled in the shape of a pudding, if it puts on a cold place in the character of the resin currently used for ink. If warming in hot water etc. is carried out and ink is warmed, ink will return to the original state. Physical properties do not have influence.

Although he wants PVC Free ...

As ink which has a track record as PVC Free, there are TSN super-Slow Dry, MS-8, 3000 super-Slow Dry, etc. Since printing aptitude and drying characteristics are a little bad, there is no demand of PVC Free in Japan at present.

Would you teach combination, although he wants to perform mixing colors at his company?

We can announce you mixing-colors combination to the visitor who shipped in the past.

Although ink spreads ...

The thing of combination with much メジューム may have the low viscosity of ink, and a blot may occur. Please change to メジューム and carry out 5-10% addition of Care39, using an 850 half ton base. mixing colors -- in the case of elegance, please consult to our company.

If the ink made from the SEIKO advance is printed in piles on the ink of the other company, although flipping will occur ...

Ink of our company is excellent in the ink in consideration of transparency or overcoat nature, and there is many ink which is using the thing of a non silicone system for an antifoaming agent. Example SG700, JET-V1, and VIC(N) CAV May Van and CAV transparency, specular surface ink Since the thing of a silicone system is used for the antifoaming agent of the ink of the other company in many cases, silicone has floated in the printing surface, and if ink of our company is printed, flipping will occur. Flipping will be subsided if 0.5-1% addition of silicone system additive agent Care20 or Care50 is carried out at ink of our company. When transparency is required, please change all the ink into the thing of our company.

Although ink foams ...

Although the antifoaming agent is put into ink, since it floats in the ink surface, a foaming agent may be insufficient, without being well mixed, unless it agitates before use. Please add about 0.5 to 1% of the antifoaming agent (refer to catalog) which suited the ink type.

Although a fine hole opens in ink ...

When the viscosity of ink is hard, a blur and a pinhole may occur. Please add a silicone system antifoaming agent to see I have the quantity of a dilution solvent increased.

Although hardening is insufficient and not being solidified in inside ...

UV ink is hardened when ultraviolet rays hit. The color which reflects and absorbs ultraviolet rays, such as white and black, has a case where it does not solidify, in a not much deep color or thick film printing. Please examine again by adding the photo polymerization initiators (UV635 etc.) which make a color thin, which make emulsion thickness thin and which raise the output of UV irradiation machine.

If a ground prints UV ink on black, although it will not solidify ...

Since black absorbs ultraviolet rays, reflective UV light from a material cannot be used, but hardening may worsen. Please examine again by raising the output of UV irradiation machine.

Although are stuck the first stage and it exfoliates in several months, when UV printing is carried out on PC ...

Even if UV ink exposes it to ultraviolet rays, it hardens only 80-90%. The remaining 10-20% is gradually hardened with progress of time. Moreover, since it contracts at the time of hardening, UV ink may exfoliate in several months. Since adhesion nature changes with materials, we recommend you the thing not only initial adhesion but several months after to do for a check test.
