Paper Specifications and Quality
1. What are the differences between 70GSM and 80GSM paper?
70GSM paper is relatively thinner and lighter, weighing 70 grams per square meter, while 80GSM paper is thicker and heavier, with a weight of 80 grams per square meter. 80GSM paper usually feels more substantial, has better stiffness, and is less likely to show ink penetration during writing and printing.
2. Is the paper size standard A4? What is the error range?
Yes, it is the standard A4 size, which is 210mm×297mm. Generally, the size error is within ±1mm, which is considered normal and will not affect normal use.
3. What types of documents are suitable for printing with these two GSM papers?
70GSM paper is suitable for general daily office document printing, such as ordinary text files and internal materials. In addition to office document printing, 80GSM paper is more suitable for occasions with higher requirements for paper quality, such as important contracts, color printing, double - sided printing, and documents that need to be stored for a long time.
Printing Effects
1. Will paper jams occur during printing?
Double A printing paper has passed strict quality inspections. The paper has high flatness and good stiffness, and generally, paper jams will not occur. However, the printing effect also depends on the condition and settings of the printer. If the printer itself has malfunctions or improper settings, paper jams may still occur.
2. For inkjet printing and laser printing, which GSM paper gives a better effect?
For inkjet printing, both 70GSM and 80GSM papers can perform well. However, 80GSM paper has better ink absorption, allowing the ink to penetrate and dry better, with less ink bleeding. It also has a higher color reproducibility. For laser printing, both GSM papers are applicable. When printing high - quality pictures or detailed charts, 80GSM paper may produce a better effect due to its better texture.
3. What is the whiteness of the paper? Does it affect the printing effect?
Double A4 printing paper usually has a high whiteness, which can provide a clear and vivid printing effect, making text and images more eye - catching. High whiteness can also enhance the saturation and contrast of colors, making the color - printing effect more vivid and realistic.
