Abstract

PURPOSE: A method and an apparatus for offset printing for kraft paper bags is provided to improve the quality of printing by applying high quality printing technique to a kraft paper bag of low cost, thereby achieving mass production of offset printed kraft bags. CONSTITUTION: A method for offset printing for kraft paper bags includes the steps of controlling a tension by a tension controller as a kraft paper is arrived at the tension controller from a winding roll(1) via a winding roll supporting die(11), reading photographs in a continuous process by a scanner to disintegrate the photographs into four colors (red, blue, yellow and black), making printing plates with the disintegrated four colors via a color separation work of a film, passing through respective red, blue, yellow and black color printing parts(31,32,33,34) of a high sensibility offset printer(3) which synthesizes and prints various photographs with high precision for printing the four colors by overlapping, and winding on a winding roll(4) after the printing.

Description

The offset and method for offset printing of craft paper and its device {The apparatus and method for offset print of craft paper}

The present invention relates to an offset printing method and apparatus thereof for kraft paper, and to explain in detail, a roll of the printed roll is re-printed through a method of applying a offset type machine and rewinding a mass of a certain standard printing at low cost. The present invention relates to a mass-produced device and a method using the same.

In general, as an offset press, commercial offset presses use a printing method that feeds and feeds standardized cutting paper, not a roll, in a sheet. The printing paper size is different from the printing plate in order to print several specifications. Since the same setting and sheet feeding method, there was a problem that it is not practical to adapt the machine, and another rotary offset printing machine is a roll dosing method, which is limited to mass production of a limited number of printed materials such as newspapers. Machines that require high performance and high precision as a targeted printing press have been widely used.

Korean Patent Publication No. 1277782 is a printing paper conveying apparatus which has a plurality of crimpers in a chain and turns the printing section and the delivery section from the paper feeding section, and improves the conveying accuracy of printing paper, and uses a preliminary roller equipped with heating means. It is an offset printing machine capable of high-definition printing by preventing deformation of the paper, measuring means for adjusting and measuring contact pressure between rollers, and air cleaning means for cleaning the surface of the printed paper. ,

Korean Patent Publication No. 188463 discloses offset printing with a wetting system and an inking system simultaneously with one or more printing units that draw a printing plate and a transfer container, each of which forms a method-specific working layer, that is, a water absorbing layer and an ink absorbing layer. Is about

In the Korean Utility Model Publication No. 99-38541, one side end of the paper feed is provided at the front end of the variable guide part so that the feeding of paper is not prevented even if the end of the paper is inserted into the base plate and the bottom of the leaf spring to align the paper feed. It relates to an offset printing machine which is formed to have a width wider than the moving range of the variable guide part, and is easy to clean the rollers and the disassembly of the variable guide part and the removal of the jam feeding according to the occurrence of paper feed jams.

The conventional techniques are a single sheet feeding method, and the offset press is a roll dosing method can print a large number of prints of a certain standard, such as a newspaper, it can be printed in high-quality, large-scale, crisp paper on a thin paper such as kraft paper There have been problems such as cost increase.

In order to solve the above problems, in the present invention by applying an offset-type machine in a method that can mass-produce the printed rolls back to the umbilical cord through the method of rewinding the mass production of a certain standard at a low cost High-quality offset Printing quality can be mass-produced by applying to low-cost printing zones that are currently distributed at low cost, and offset printing of kraft zones that can produce zones of various specifications as a system from printing to cutting of shape folding It is an object of the present invention to provide a method and an apparatus thereof.

In order to achieve the above object, the present invention is to apply the offset-type machine to produce a certain size of printing at a low cost mass production by rewinding the printed roll through the rewinding method to the mass production 2 The present invention relates to an offset printing method of a kraft zone and a device therefor.

Conventionally, the flexographic printing method has been used as a method of printing on a zone using the resin plate. The reason is that the first roll must be mass-produced, so the advanced printing method is required to introduce the offset printing method for printing high quality colors. As the printing method cannot be used, it is impossible to print more precisely than the offset printing, and the printing method used in the present zone is that the photo composite quality is remarkably inferior.

In addition, the conventional printing apparatus is a machine made to produce zones of various specifications by folding and cutting the paper in a roll state through a printing press, and is a machine made to produce various specifications. The cylinder and the gear for attachment, the gear of the cutter part, etc. should be replaced according to the standard, and the production of the various specifications as described above is not mechanically high. Therefore, the method of printing with four colors overlapped is not appropriate in terms of printing quality due to mechanical error, and the shape is formed and cut by the roll administration method. come.

The present invention is a significant improvement over the conventional printing method as described above,

The current printing technique invented a low cost, high quality printing method with a printing technology that can apply photo quality as it is with the most advanced printing method. In other words, the photo is read by the scanner's equipment, and it is decomposed into four colors (red, blue, yellow, and black). Photographs can be synthesized and printed, and manufacturing costs are reduced compared to other printing costs.

According to the present invention, unlike the conventional method, kraft paper is printed in a continuous process through a roll and then wound through a high-sensitivity offset printing machine, and then wound into a roll. Then, the kraft paper on the printed roll is folded and cut to process a zone to produce a printed zone. In the related art, the printing process and the grounding process are connected in series. However, when a jam occurs in the grounding process, the printing process and the grounding process are delayed at the same time. However, in the present invention, the printing process and the grounding and packing process are separately configured so that the speed is improved than before.

Hereinafter, the present invention will be described in detail through examples.

Example

Kraft paper is rolled into a continuous process to read photos into the scanner's equipment, which is then disassembled into four colors (red, blue, yellow, and black), which are separated by four separate film printing plates, and the four colors overlap to print. After adjusting the tension through the tension regulator (2) the roll (1) wound kraft paper to be printed through a high-sensitivity offset printing machine that can print a variety of photos synthesized, and then, the red printing unit (31), After passing through an offset printer 3 for printing the blue printing part 32, the yellow printing part 33, and the black printing part 34, and then winding it on the printing paper winding roll 4, the winding roll 4 ) Is transported to the ground folding and wrapping paper manufacturing process, folded into a zone shape, and then cut to produce printed kraft paper.

Hereinafter, with reference to the drawings will be described in detail.
