Analyze color inkjet printer

Color inkjet printers can be regarded as products that have developed rapidly in recent years. Major manufacturers have been constantly introducing new technologies. Of course, each brand has its own advantages and disadvantages, but everyone says that their technology is better than others! For these new technologies and specifications, what exactly are the data we should care about? How do we use common sense to verify it? I would like to take this opportunity to discuss with you all. What are the real reasons for affecting the output quality?

Resolution is the printer's most frequently emphasized specification, and the specifications marked by the printer can be said to grow in multiples over time. Let's start by looking at what dpi is. Dpi is an abbreviation, the original text is dot per inch, which means how many dots per inch. The days when the early printers marked 300dpi or 360dpi are no longer visible, and many printers have already claimed more than 2000dpi! What is the significance of such a high dpi? Recently I saw a printer that has a print resolution of 600 dpi, which is 600 points per inch. However, they have a technique that allows a slight change in the size of each point. The diameter of a dot can range from 1/2400 to 1/600 inch because the finest point can reach 1/2400 inch, so it is claimed to have 2400 dpi.

This statement is far from the original definition of dpi, because even though each smallest point can reach 1/2400 inches, in one inch, 600 dots of 1/2400 inches in diameter still have only 600 points per inch. Point, so this print resolution is actually only 600dpi. Of course, this emphasis on the ink dot diameter is still a relatively well-known manufacturer, and there are some manufacturers who have emphasized the volume of ink droplets since long ago. The volume of ink droplets depends on the viscosity of the ink to represent adhesion. The area on the paper may be too complicated for the conversion formula, or some printer manufacturers deliberately blur the consumers and use this method to mislead consumers.

In addition, the purchase of friends should pay attention: seeing is not necessarily true! A professional person must know that some of the print images displayed to reflect the performance of a particular printer are for reference only, because there is so much learning! First of all, how to set the basic computer environment settings? If you use professional image-drawing software, such as Photoshop, to use this software to read a document sent by someone, sometimes a dialog box appears. This is different from the basic environment setting of your computer. To change the color mode. The meaning is that the color mode is different, the settings are not the same, the color mode can be converted through complex functions in order to obtain a more consistent visual point of view. In fact, different color definitions can basically show different abilities.

The most important issue is the question of what type of image format to print. Some renderings have undergone professional adjustments. These graphics have undergone considerable processing regardless of saturation or hue. Some of the drawings are even one pixel and one pixel to modify the color values ​​one by one. If you know the mystery of the inside, can you still expect such good results when playing your photos in your home? Maybe you will ask, it is always objective to compare with the graphics on the display computer! The answer is still negative. Based on environmental constraints, computers on display occasions are difficult to match with the external environment, and the setting of the computer environment is not consistent. Therefore, the results of the display will differ.

So how much more resolution, resolution is not important? Taking the general magazine output as an example, the document delivered to the output center has a resolution of 300 dpi. That is, the magazine outputs about 300 dpi resolution. It is worth noting that we are looking at the resolution rather than the resolution. The resolution of 300dpi represents the ability to output 1/300 inch lines, that is, 0.085mm lines. This result is already quite good. In my experience, the current output resolution of the printer is above this level, and some have even reached a level of nearly 460 dpi. Under such circumstances, to continue to increase the print resolution of the printer, it is actually an act of putting the cart before the horse. The improvement of the resolution can only improve the exquisite degree of printing, but if the photocopies between the colors are not correct or the saturation is not high enough, the result of the output is very easy to make people feel different.
