CN102825941A - Matte finishing process for metal printing product - Google Patents

Abstract

The invention discloses a matte finishing process for a metal printing product. The matte finishing process comprises the following steps of: 1, coating gloss oil on a printed tinplate semi-finished product at a early state, wherein the thickness of a dry gloss oil film is 4-5 microns, and the drying temperature of the gloss oil is 170-175 DEG C; and 2, printing an extinction ink layer on the printed product coated with the gloss oil in the step 1, wherein the use amount of extinction ink is at least 1.5 g/m<2>, the drying time in a printing process is 150 DEG C, and the drying time is 10 minutes. The matte finishing process disclosed by the invention has the advantages that the step of coating the gloss oil is added into the printing procedure, one protective oil layer is coated on the surface of the printed product, and then the extinction ink layer is printed, so that the printed product can express a matte effect, the surface of the printed product does not have coating grains, and the printed product is very fine and artistic, thereby guaranteeing the quality and the grade of the product.

Description

The inferior light treatment process of tin graphed sheet goods

Technical field

The present invention relates to tin graphed sheet technology, especially relate to the inferior light treatment process of a kind of tin graphed sheet goods.

Background technology

The tin plate printing goods generally need glazing (full light) to handle after according to the printing of customer demand pattern, complete inferior light is handled or local inferior light is handled.Complete inferior light is handled the general coating semigloss oil that adopts and is reached matt effect.Because semigloss oil and plant issue though can make printed matter surface present matt effect, lines also can occur being coated with simultaneously, make printed matter surface fine and smooth inadequately, the quality class descends; Cause part client rejected product, lose the high-grade client of part, bring loss to enterprise.

Summary of the invention

The object of the present invention is to provide a kind ofly can reach matt effect, simultaneously the fine and smooth inferior light treatment process of tin graphed sheet goods in surface.

For realizing above-mentioned purpose, the present invention can take following technical proposals:

The inferior light treatment process of tin graphed sheet goods of the present invention, it comprises the steps:

The first step, oil polish on the tinplate semi-finished product that print early stage, gloss oil build 4-5 μ m, 170--175 ℃ of gloss oil bake out temperature;

In second step, with printing delustring China ink layer on the printed matter of crossing oil polish on the first step, delustring China ink consumption is 1.5g/m at least ², the bake out temperature during printing is 150 ℃, drying time got final product in 10 minutes.

The invention has the advantages that in printing process, to have increased and cross the gloss oil step; Can make printed matter surface be coated with the layer of protecting oil reservoir; After republishing delustring China ink layer, printed matter both can demonstrate matt effect, and lines also can not appear being coated with in the surface; Very fine and smooth attractive in appearance, make product quality and class be able to guarantee.

The specific embodiment

The inferior light treatment process of tin graphed sheet goods of the present invention, it comprises the steps:

The first step; Oil polish (is example with the 25G oil polish) on the tinplate semi-finished product that print early stage, gloss oil build 4-5 μ m, too thin meeting loses the protective effect of gloss oil to ink lay; The too thick waste that then not only can cause gloss oil also can make follow-up matt effect not obvious; 170--175 ℃ of gloss oil bake out temperature; Can increase the adhesive force of delustring China ink in the follow-up delustring operation like this;

Second step was transported to printing delustring China ink layer on the printing machine with the printed matter of crossing oil polish on the first step, and the bake out temperature when noting the delustring ink print is controlled at 150 ℃, and drying time was not less than 10 minutes, and the consumption of delustring China ink is 1.5g/m at least ², otherwise matt effect is not obvious.

Reach whole matt effects with the delustring ink print, but not, improved the quality of goods, satisfied client's demand through being coated with the technology of semigloss oil.Like in August, 2012; The application people prints a collection of green (illusion tree) 365 new product moon cake boxes for Xinxiang honey degree Food Co., Ltd; The firstling that adopts explained hereafter of the present invention to go out had both obtained client's satisfaction; And appended order, developed a plurality of new packings, for unit has created considerable economic.

Claims (1)

1. the inferior light treatment process of tin graphed sheet goods, it is characterized in that: it comprises the steps:

The first step, glazing oil on the tinplate semi-finished product that print early stage, gloss oil build 4-5 μ m, 170--175 ℃ of gloss oil bake out temperature;

In second step, with printing delustring China ink layer on the printed matter of crossing oil polish on the first step, delustring China ink consumption is 1.5g/m at least ², the bake out temperature during printing is 150 ℃, drying time got final product in 10 minutes.
