Problems solved by technology

Although the invention reduces labor costs, it cannot solve the problem that the ink used in printing is toxic and will contaminate the packaged food, medicine and cosmetics; and it is volatile and has a strong pungent smell, which will pollute the environment and affect workers. Physical health issues, for this, we propose a flexographic printing process

Embodiment 1

[0033] First of all, according to the inking area of ​​each color of the printed matter, it is estimated based on daily experience how many lines per inch anilox roller can be selected to meet the amount of ink imprinted, and secondly, according to the ink absorption of the printing material, during the preliminary proofreading process, observe For the hue, saturation, etc. of each color printing, select the appropriate anilox roller; then select the ink: use the color that has been determined on the color scale, and use the basic color and mixed color printing to achieve the required printing results. The selected ink has Generally, new water-based inks and ultraviolet inks are selected for the ink viscosity and surface tension that are suitable for the printing material; then the surface tension of the printing material is checked: the tension of the material is tested with a dyne value test pen and surface tension measurement liquid, and the plastic film When the surface ten...

Embodiment 2

[0035] In embodiment one, add following operation:

[0036] The number of lines of the ceramic anilox roller in step (1): solid version 100-160 lines / cm, text line version 160-240 lines / cm, anilox version 220-320 lines / cm, 280-400 lines / cm; step The ink selected in (2) needs to have a sufficiently high ink solid pigment content, and the drying speed of the ink is compatible with the printing speed.

[0037] First of all, according to the inking area of ​​each color of the printed matter, it is estimated based on daily experience how many lines per inch anilox roller can be selected to meet the amount of ink imprinted, and secondly, according to the ink absorption of the printing material, during the preliminary proofreading process, observe For the hue, saturation, etc. of each color printing, select the appropriate anilox roller, and the number of lines of the ceramic anilox roller: 100-160 lines / cm for the solid version, 160-240 lines / cm for the text line version, and 220-22...

Embodiment 3

[0039] In embodiment two, add following operation:

[0040] In step (4), the worn squeegee blade should be replaced in time, otherwise the quality of ink transfer cannot be guaranteed; in step (5), medium and low density 1115 double-sided tape is used for screen printing and thin line printing, and text, and line printing Medium-density 1015 double-sided tape is used when printing, and high-density 411DL double-sided tape is used for field printing.

[0041] First of all, according to the inking area of ​​each color of the printed matter, it is estimated based on daily experience how many lines per inch anilox roller can be selected to meet the amount of ink imprinted, and secondly, according to the ink absorption of the printing material, during the preliminary proofreading process, observe For the hue, saturation, etc. of each color printing, select the appropriate anilox roller, and the number of lines of the ceramic anilox roller: 100-160 lines / cm for the solid version, 16...

Abstract

The invention discloses a flexograhic printing process which comprises the following steps: selecting an anilox roller: firstly, estimating the ink amount to meet the print by selecting the anilox roller with line numbers per inch by means of daily experience according to the inking area of graphics of colors of a printed matter, and then observing hue, saturability and the like of prints of colors in an initial verifying chromatographic process to select a proper anilox roller according to the ink absorbing amount of a printed material; and selecting printing ink: achieving a needed printingresult by employing a basic color and a mixed color by adopting colors set on color marks, wherein the selected printing ink has printing ink viscosity and surface tension adaptive to the printed material. By employing novel aqueous printing ink and ultraviolet printing ink, the flexograhic printing process not only is environment-friendly and has the quality, but also solves the problem that theprinting ink used for printing is toxic and pollutes packaged articles such as food, medicines and cosmetics. The flexograhic printing process solves the problem that print is volatile, has relativelystrong pungent smell and pollutes the environment and affects the human health of workers.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a flexographic printing process. Background technique [0002] Printing is a technology that transfers the ink to the surface of paper, fabric, plastic, leather and other materials through plate making, ink application, and pressurization to copy the contents of the original manuscript in batches. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink. [0003] Traditional solvent-based inks are widely used in the printing industry. Solvent-based inks are composed of pigments, binders, solvents, fillers and auxiliary agents. The solvents used are mainly aromatic hydrocarbons, esters, ketones, ethers, etc. Organic solvents, most of these solvents are toxic and will contaminate the packaged food, medicine and cosmetics; they are volatile and have a strong pungent smell, which will pollute the environment and...
