Print on cardboard

Printing paper is the paper used for printing:printing methods are different:the performance of the paper used is also different. For example:the printing of newspapers and magazines newsprint and printing books letterpress paper:good ink absorption and impervious to print; offset paper for color printing:there is a high rate of water absorption deformation and expansion; paper used for gravure printing:paper:paper surface is delicate:printed lines clear and realistic.

Paper has a long history of development:roughly give you a classification

The first: according to the use:can be divided into printing paper:printing and copying paper:drawing paper:living paper and so on;

The second kind: according to the production:can be divided into uncoated paper and coated paper. Copperplate paper:inkjet printing paper is a kind of coated paper;

The third kind: according to the material:it can be divided into traditional plant fiber paper:PVC paper , PP paper and so on.

1:offset printing paper: the old name of Dowling paper. Mainly for offset printing presses or other printing machines for printing:such as books:inserts:etc.:the surface does not look very smooth. If it is double-sided offset printing paper:can be referred to as “double offset paper”.

2:coated paper: commonly known as “coated paper”:”pink paper”. Coated paper surface coating:with good optical properties and printing performance. Can print more bright colors:common fashion magazines:posters:albums:most of this type of paper.

3:electrostatic copy paper: this is the office of the most commonly used A4 copy paper:is a wood pulp as the main raw material made of paper. Electrostatic copying technology uses a dry powder heated fixed development method:so the flatness of the paper:tightness:moisture content and electrostatic properties are required.

4:white cardboard: refers to completely with bleached chemical pulp manufacturing and fully sized single or multi-layer combination of paper. This type of paper smoothness:stiffness:good:neat appearance and good uniformity:commonly used to make business cards:packaging:invitations and so on.

5:corrugated paper: is made of hanging paper and corrugated paper through the corrugated stick processing and the formation of wave-shaped corrugated paper bonded to the board:corrugated cardboard boxes are made of corrugated cardboard:is the most widely used paper container packaging. So do you know what are the advantages of corrugated paper? Corrugated paper has good shock absorption and mechanics due to its own corrugated structure:and it is lightweight:versatile:low freight:recyclable and so on. The printing methods of corrugated paper include letterpress:gravure and lithography.

The material used for TOPWON’s display racks is mainly corrugated paper:which has more advantages.

1:low transportation costs:and easy to realize the mechanization and automation of packaging and transportation.

2:It can be combined with various kinds of coverings or moisture-proof materials to greatly expand its scope of use.

3:the waste box is easy to recycle and reuse:in line with environmental requirements.

4: It can adapt to the decoration printing of various types of cartons:and can well solve the problem of commodity protection and promotion.

5: It has many good protection functions for the packaged goods. For example:moisture-proof:heat dissipation:easy to handle.

6:the specifications of the carton and the size of the change is easy to realize:the carton can quickly adapt to the packaging of various types of goods.

7:sealing:bundling are convenient:easy to work:improve efficiency.

8:the corrugated structure is similar to the arch structure:can play the role of shock absorption:has good mechanical properties. Light weight and good structural performance.

Five major factors affecting printing

First:cardboard

The first step in carton printing is to choose a high-quality carton material – cardboard. The quality of the carton mainly depends on the quality of the paper:so it is very important to choose the right paper. Good cardboard should have a high gloss:and smooth and flat:conducive to the transfer of ink and fixed. In addition:the tension of the paper is also an important factor in determining the quality of carton printing:too much or too little tension will lead to uneven ink transfer:affecting the printing effect. So the permeability of the cardboard:ink absorption:the thickness and smoothness of the cardboard:the four properties of the surface paper:respectively:will cause leakage:dent and other printing bad.

Second:the printing plate material


1:printing plate materials. Anyone engaged in printing knows that printing text patterns on paper needs to be made of resin plate. Resin plate is made of resin:with the plate material aging is caused by too much time. Wear and tear:weak elasticity. Therefore:it is easy to cause poor coloring:affecting the printing effect.

2:ink: the quality of ink also directly affects the printing effect. Ink stability:permeability:fluidity and viscosity of the four aspects of quality standards is the key. For example: the viscosity of the ink:viscosity is good:the ink is easy to adsorb to the surface of the cardboard:printing is in place:the effect is good:viscosity is good if not good:it is easy to lack of ink.

Third:equipment


Rubber roller rubber aging:elasticity disappears:anilox roller wear:resulting in ink can not flow well to the printing plate:resulting in poor printing printing is not clear. The balance of the anilox rollers and the bottom rollers are not well adjusted resulting in white edges:white and other phenomena

Four:Operator

1 proficiency: the machine needs to be operated:the printing operator’s proficiency directly affects the quality of printing. Experienced printing master:after hanging a good resin plate:he will start printing a sample for comparison and adjustment. The effect printed through the roller can be adjusted for the best. Novice need a long time to familiarize themselves with the equipment:may be adjusted many times resulting in poor printing results.

2 responsibility and quality consciousness: machinery does require human operation:but printing out the product in addition to technology:but also need someone’s sense of responsibility and quality consciousness:a person’s quality consciousness and responsibility is not high:printing out the product may not be so good.

Five. Environment

Dust and temperature and humidity:the dust of the production environment is more likely to stick to the resin plate leading to the appearance of dew white or burr quality accidents:temperature and humidity will affect the concentration of ink.
