The minimum heating temperature for printing on coated paper

Coated paper requires an appropriate temperature when printing, and each printer has a different heating bar, which is also different from the heating temperature of many coated papers. Therefore, you must first master the minimum heating temperature required for the coated paper you use.

What is the minimum heating temperature for coated paper printing?

During the printing process of coated paper, high-quality photos can be printed when the temperature is between 60 and 68 degrees, and high-quality photos cannot be printed at 58 degrees, so 60 degrees is the minimum heating for coated paper printing. temperature.

High-quality photos can be printed at 60 and 68 degrees

Why should we determine the minimum heating temperature for printing on coated paper?

Since 60 degrees can print high-quality photos, 62 degrees can do the same, so why determine the minimum heating temperature for printing on coated paper?

1. Reduce the upturning of paper corners in heating printing

When the temperature is low, the quality of the printed photos is not good, but if the temperature is too high, the paper will be deformed by heat during heating and printing. Firstly, the four edges and four corners of the paper will be deformed, which directly affects the quality of printing; secondly, the deformed corners will directly rub against the nozzle, causing the corners of the printing paper to contaminate the ink, and even cause the nozzle to print The process was interrupted, resulting in the scrapping of printed works.

2. Minimize the impact of heating on the life of the print head

The temperature of heating printing must affect the life of the print head. The temperature is high and the impact is relatively large; the temperature is moderate and the impact is reduced, or even not affected. Because of this, be sure to repeatedly test the minimum temperature of coated paper before printing photos.

Different papers require different printing temperatures

The temperature required for printing on common coated paper of different brands is generally about 60 degrees, and the temperature difference between each other is about 5 degrees. The difference in temperature required for printing between embossed coated paper and some special coated paper is relatively large, and some differ by more than 10 degrees.

From the perspective of use, coated paper with low required printing temperature should be the first choice, because the nozzle of this coated paper is still smooth after printing for a whole day. Taking the R290 printer as an example, it can still print 6 kg of ink after heating. Make the nozzles in good condition, and the coated paper with high printing temperature is easy to break during printing.

The printing temperature required for different papers is also different, because we can ask for a sample printing test to compare before printing, especially embossed coated paper, the same texture paper may also require a different printing temperature.

Different brands of ink require different printing temperatures for paper

This problem has not attracted everyone's special attention, so that there will be ink stacking due to insufficient temperature during heating printing, or printing disconnection due to too high temperature, which is often called a plug. [next]

What exactly is coated paper?

Coated paper is a paper made from coating base paper after coating and decoration processing, and has a targeted printing ink coating on the paper surface. Coated paper is a common name, and the official name should be printing coated paper, which is one of the main papers used by printing houses.

Coated paper is widely used in real life, such as the calendars we see, book covers, illustrations, art books, picture books, etc., almost all of them are coated paper, various beautifully decorated packaging, paper handbags, labels Coated paper is also widely used for stickers and trademarks.

Coated paper includes single-sided high-gloss coated paper, double-sided high-gloss coated paper, double-sided matte (matte) coated paper, high-gloss / matt coated paper, embossed coated paper and special coated paper.

A. Single-sided high-gloss coated paper

Single-sided high-gloss coated paper generally appears in coated paper of more than 200 grams. This kind of paper is used in inkjet printers. The photo-coated side has high print quality, and the uncoated side photo print quality is average, so it is generally Used for printing business cards, it is not recommended to use this kind of paper for printing photos.

B. Double-sided high-gloss coated paper

Double-sided high-gloss coated paper is coated paper coated on both sides, with a thickness from 100 g to 350 g. The effect of printing on both sides of this paper is the same.

The specular of coated paper is generally relative to matte. Its specularity is difficult to compare with our commonly used specular RC photo paper, but the specular of coated paper does have the difference between specular and subspecular. The specular we commonly see is actually Sub-gloss, and real high-gloss coated paper can be compared with high-gloss RC photo paper.

C. Double-sided matte (matte) coated paper

Matte (matte) coated paper on both sides is matte on both sides. Although it has no gloss on both sides, it is definitely different from card paper because the surface of matt coated paper is coated and the quality of printed photos is also very high .

D. High gloss / matt coated paper

High-gloss / matt coated paper is glossy and matte on the surface of the paper. Unlike single-sided high-gloss coated paper, it is coated on both sides of the paper, and both sides can print photos and print high-quality photos on both sides.

High-gloss / matt coated paper is easy to distinguish from single-sided high-gloss coated paper. Matte coated paper must be printed by heating or ink will be piled up, while card paper can be printed without heating, but the quality of photo printing is not high.

The back of the highlight is matt

E. Embossed coated paper

Embossed coated paper is to press many different patterns on the surface of the paper. Due to the different patterns, there are several types of coated paper. For example: butterfly shadow pattern, rich pattern, fine cloth pattern, wind tail pattern, water ripple, quarry pattern, lotus pattern, tea pattern, inspiration pattern, concentric pattern, pear pattern, wind tail pattern, jazz pattern, star rain pattern, The new scale pattern, bamboo silk pattern, etc., the embossed coated paper also has high gloss and matt.

Embossed coated paper improves its decorative effect by embossing, making the paper more textured and enhancing and enhancing the expressiveness of photos. But it must be noted that most of the texture of embossed coated paper is not completely suitable for photo printing, because some textures will affect the delicateness of the portrait, such as bamboo silk coated paper, this horizontal line stripe is easily reminiscent of the nozzle. Broken lines and printed photos with horizontal stripes.

F. Special coated paper

The special bond papers pointed out here are mainly various colored bond papers, among which are various embossed bond papers with glossy and matt sides, and gold and silver bond papers.

The speciality of special coated paper is colored, gold, silver, rice gold, platinum, etc. These special coated papers are more suitable for printing recipes, business cards, etc., and are not suitable for printing photos, because the color of the paper will dilute the people in the photos Or the scenery, so that it looks gray and not bright.
