Study on Printing Quality of Different Properties of Paper by Inkjet Printing (I)

壹、Introduction

First, research motivation

The 21st century is an era of rapid technological advancement. With the advancement of computer science and technology, people are increasingly relying on computers to help deal with the work at hand. The increasing scope of computer applications has caused the popularity of digital printing and the inkjet market. Therefore, it became the mainstream, and the technical principle of inkjet printing was invented long ago. However, it was only used in printers since the 1970s. Nowadays, ink jet printing is mainly used in printers, and it has gone from monochrome printing to color printing. Printed from four colors to six colors, inkjet printing technology is becoming more and more mature. It not only saves manpower, but also can quickly cope with the urgent time constraints. The rapid expansion of the inkjet printing market can even be changed by specialization. From the past professional field to the popularization, so a variety of printing technologies have been continuously developed, there are many factors that affect the color printer market, such as price, resolution, support software, color quality, application range and Education and training are all important factors. Because the future market is quite large, users are There are also many well-known manufacturers in the world such as HP, EPSON, CANON, etc., all of which are responsible for the development and improvement of these elements to introduce better printers to meet the needs of consumers, so that the quality of printing can meet everyone's desire. of.

Second, the purpose of the study

Due to the rapid development of inkjet printing technology, creating a wide range of printers, so almost every company and family has one, or even more, bring us many conveniences, and there are many models on the market for consumption. To choose, regardless of the label, the average user is very concerned about the color performance, resolution and other conditions, but one thing is often overlooked, that is, the choice of paper will not pay attention, many people think The price of expensive paper can show color, but in fact it is not entirely the same, it is because the nature of the paper will affect its print results, so most people pay little attention to the type and nature of the purchase, that print color It's not bad, but it won't be noticed that there are other factors, so we chose to print the No. 1 printer and the No. 2 printer to make experiments, use the color blocks as printing samples, and then measure and study the different types of paper. The relevance makes it easy for consumers to know that different papers are printed with different effects, so users can be aware of the different properties of the paper. It will affect its printing effect, in order to have the correct choice.

Third, research hypothesis

Assume that printing different quality papers with No. 1 printer and No. 2 printer will have different printing quality effects. According to the quality analysis of the three different properties of whiteness, gloss, and opacity, whether the Lab value, the LCH value, and the calculated color difference study have a significant relationship to make a judgment.

Fourth, research issues

With the No. 1 printer and the No. 2 printer, the print quality of different types of papers is as follows:

1. What are the values ​​of the whiteness, gloss, and opacity of different papers?
2. Is the Lab value and LCH value represented by the color patches printed on the paper analyzed?
3. What are the relationships between Lab values ​​and LCH values ​​and whiteness, gloss, and opacity?
Is there a difference in print quality between the 4.1 printer and the 2 printer inkjet printer?

V. Research limitations

1. We only change the nature of the paper. They are whiteness, gloss, and opacity. We analyze the quality of the paper. We fix it on the screen, software, and hardware, so we only know that the 1st and 2nd printers are The relationship between the nature of the sheet of paper and the differences between the two printer technologies does not reveal the untested paper and other models. We can only select one printer for each time because of the time required for funding.

2. This experiment is to investigate the three factors of paper's opacity, whiteness and gloss. Due to the lack of experimental equipment, other factors cannot be discussed.
