Talking about the Lowest Heating Temperature of Coated Paper Printing (I)

Coated paper requires proper temperature when printing, and each printer has different heat bars, and there are differences in the printing temperature required for many coated papers. Therefore, you must first master the minimum heating temperature required for the coated paper itself.

What is the minimum heating temperature for coated paper printing?

Coated paper can print high-quality photos when the temperature is between 60 and 68 degrees during the printing process, and it cannot print high-quality photos at 58 degrees, so 60 degrees is the minimum heating of coated paper. temperature.

High quality photos can be printed at 60 and 68 degrees

Why do you want to determine the minimum heating temperature for coated paper?

Since 60 degrees can print high-quality photos, as well as 62 degrees, then why should we determine the minimum heating temperature for coated paper?

1, reduce the heating paper in the paper upturned

The temperature is low. The quality of the printed photo is not good, but if the temperature is too high, the paper in the heated print will be heated and deformed. Firstly, distortion occurs on the four sides and four corners of the paper. This directly affects the quality of the print. Secondly, the heat-deformed corners rub directly onto the nozzle, causing the corners of the printed paper to be contaminated with ink, and even cause the nozzle to print. The process is interrupted, resulting in the rejection of the printed work.

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

The temperature of the heated print must affect the life of the print head. The temperature is high and the influence is relatively large. When the temperature is moderate, the influence is reduced or even not affected. Because of this, it is important to repeatedly test the lowest temperature of coated paper before printing it.

Different papers require different print temperatures

Different brands of ordinary coated paper printing temperature is generally around 60 degrees, the temperature difference between each other is about 5 degrees. The difference between the temperature required for printing between embossed coated paper and some special coated papers is relatively large, and some are more than 10 degrees apart.

From the use point of view, coated paper with low printing temperature should be the first choice, because such coated paper will still be smooth after printing for a whole day. Take the R290 printer as an example, it can still heat and print 6 kg of ink. The nozzles are in good condition, and the coated paper with high printing temperature can easily break during printing.

The printing temperature required for different papers is also different, because we can request a sample print test to compare before printing. In particular, embossed coated paper, the same printed paper may also require different printing temperatures.

Different brands of ink have different printing temperatures for paper

This problem did not arouse everyone's special attention, so that the thermal printing will appear due to insufficient temperature caused by heaping ink, or because the temperature is too high, there is a broken print line, which is what people often say plug.

What exactly is coated paper?

Coated paper is a paper produced by coating and decorating raw coating paper. There is a targeted printing ink coating on the paper surface. Coated paper is commonly known, and the official name should be printed coated paper, which is one of the main papers used by printing houses.

Coated paper is widely used in real life. For example, we can see calendars, book covers, illustrations, art books, pictures, etc. Almost all coated paper, all kinds of beautifully decorated packaging, paper handbags, labels Stickers, trademarks, etc. are also widely used in coated paper.
