Winding apparatus can peel off calendered film 3 from printed matter surface, remain to use next time.
Printed matter surface UV processing of the calendered film 10 relative to conventional art in the present invention, the calendered film 10 only needs to letter
Press polish of single overlay film with regard to that can complete printed matter surface is handled.The calendered film 10 can form glossiness on digital printing product surface
The high apparent effect of high, brightness, the apparent effect is identical with the effect that surface UV is handled.But, entered by using calendered film 10
Row press polish is handled, and technique is simple, it is to avoid using uv equipment and wait UV paint solidifications, effectively increase processing efficiency, and
Reduce processing cost.In addition, the glazing layer 200 of the calendered film 10 has wearability and high rigidity, and surface is smooth, should
Calendered film 10 can be peeled off from printed matter surface.The calendered film 10 can be reused many times, and not influence digital printing product table
Face pressure light treatment effect, reduce further use cost.
Therefore, the logarithmic code printed matter of calendered film 10 carries out the efficiency high of press polish processing and cost is low.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope of this specification record is all considered to be.
Embodiment described above only expresses the several embodiments of the present invention, and it describes more specific and detailed, but simultaneously
Can not therefore it be construed as limiting the scope of the patent.It should be pointed out that coming for one of ordinary skill in the art
Say, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
