How to Choose The ’Perfect’ Printing Paper?

In the United States, the consumption of copy paper and printing paper is nearly million tons per year.

Despite the increasing popularity of electronic documents, there is still a need for printed and photocopied paper when documents are delivered and processed. The fewer copies of paper are used in the office, the more important the scenario that we need to use it in another way. Therefore, the quality of paper is even more important.

Good copy paper can not only have excellent printing quality and long ink retention time, but also can effectively avoid jamming and static electricity, effectively reduce the damage to the copier and printer, and prolong the life of the machine.

Paper industry is a typical industry in modern industrial society. The design process is complicated and precise. The industrial chain from forestry, chemical industry, logistics, and finally to the hands of users. To sum up, we need three big steps to turn paper into printing and duplicating paper we see.

01 pulp can turn wood into pulp.

02, the pulp is prepared by physical and chemical treatment to make thin paper. This step directly affects the final strength, color and shelf life of the paper.

03 the process of interweaving and dewatering thin paper is finished, and finally the paper is cut into paper.

Generally speaking, good copy paper has the following characteristics: Conclusion: the paper quality of 80g is better than that of 70g paper. The grams of paper refer to the weight of a square meter of paper, and the weight is determined by the density of paper pulp. We purchased the same brand of different grams of paper contrast, found that 80g paper toughness, texture are significantly better than 70g paper. Of course, 80g is photocopy, but the price will be 10%-20% higher than that of 70g.

Color and lustre

Conclusion: the normal whiteness of paper is the best, and the excessive white paper is suspected of adding excessive fluorescent agent.

It is generally believed that paper is white. But it's not as white as possible. Extremely white means adding too many fluorescent and bleaching agents, so that the color of the copy paper will be extremely white, even blue, will affect reading.

In the following tests, we divided the paper into yellow, white and blue according to the color of the paper. The "blue" color of the paper will be considered a minus item.

Fiber evenness

Conclusion: paper thickness and uniformity are excellent.

This is one of the important indicators of paper quality. The uniformity of fiber distribution reflects the level of papermaking technology. In the test, I scored 0-5 points. The higher the score, the more uniform the fiber distribution.

Conclusion: the ink is uniform and the edge is clear during printing. Whether the paper is good or not must be printed in the end. Too smooth or too rough paper is not conducive to ink.
