Six wrong viewpoints for color photo printing

At present, people are using digital cameras to take pictures. They are no longer content to send digital pictures taken by them to professional digital printing shops. Instead, they use their own hands to use powerful inkjet printers or sublimation printers. Print photos directly from a digital camera. However, in the process of digital printing, due to little knowledge of digital knowledge, there are often the following kinds of mistakes!

Error 1, photos taken with a digital camera, can only be viewed in the computer

For those who have little contact with digital cameras, they easily mistakenly believe that photos taken with a digital camera can only be viewed on a computer. In fact, this is not correct. With the continuous development of digital technology, digital cameras can be directly connected to printers, and digital photos can be output through the printer. The most common printer currently printing digital photos is a color inkjet printer that can output photo images by spraying color ink onto photo paper. However, the use of inkjet printers to output digital photos has some unavoidable drawbacks, such as the relatively high cost of printing, the output of the photos saved time is not long enough, and it is easy to fade and so on. Now, the more economical way to export photos is to digitally process digital photos by using digital color expansion technology. When digital photos are washed, you only need to save the captured digital photos into a file, then copy them to a CD or disk, and then send them to a color expansion store that has a digital color expansion service.

Error 2, the higher the resolution of the photo, the clearer the print effect

Many people think that the higher the output resolution of digital photos, the more realistic the photos printed by the printer will be. Indeed, within a certain range, this view is correct. However, each photo printer has its limit print resolution. If the photo output resolution is higher than this limit print resolution, the photo print fidelity and sharpness are not improved; on the contrary, the photo output is too high. The resolution, which can only lead to a large amount of data output by the image, is very slow when the computer is transferring image data to the printer, and the printer's nozzle has to stop and wait for the image data. Obviously, Excessive image output resolution will only affect the speed of photo printing without affecting the print quality. For this reason, I suggest that under normal circumstances, please do not use ultra-high resolution photo files at will, and do not set the print resolution too high. Instead, you should find a suitable balance between the printing effect and the amount of data to ensure that With the print speed unaffected, the best photo output can be achieved.

Error 3, professional photo paper is the only guarantee for digital printing

In many people's Eyes, only photo paper can be used as a print medium to print good-looking photos. In fact, this view is biased. Although the use of special photo paper, the printed photos are better than ordinary paper. Some, but with the help of some high-end inkjet printers, such as STYLUS PHOTO EX, it can also obtain ideal photo effects on ordinary printing paper. Of course, if you have high requirements on the output quality of photos, then it is best to use professional photo paper; however, because different types of photo paper output photos are also quite different, only use a variety of different brands Photo paper, and then compare their output, in order to select the most appropriate photo paper.

Error 4, inverse relationship between photo printer output speed and photo size

In front of the author also mentioned that the higher the resolution of the photo, the larger the size of the photo, the clearer the print effect, and the lower the print speed, so many people think that the photo printer output speed and photo size There is an inverse relationship. In fact, this understanding is not comprehensive, because the speed of photo printing is not only related to the size of the photo; there are many factors that affect the printing speed, such as the processing speed of the computer system, the interface speed between the printer and the computer, and the print buffer. The size of the capacity, the size and number of nozzles of the inkjet printer, etc. will all affect the speed of photo printing.

At present, many printers have relatively weak data processing functions. This requires the computer system to process some print data. If your computer system configuration is relatively low, then the output speed of the printer may be very slow; on the contrary, those who have their own Photo printers with strong data processing capabilities can process the print data independently from the computer system during the printing process. The performance of the printer itself will affect the speed of photo printing. For example, if the interface of the printer is an ordinary parallel port, , then print high-resolution photos will often seem powerless, if replaced by the USB interface, the printing speed will increase quickly.

Error 5. The photo effects seen on the screen should be consistent with the printed results

In theory, the photo effects seen on the screen should be consistent with the printed results. This is not the case, even if it is the same digital photo, the display effect is not exactly the same in different resolutions of the screen, let alone print out the effect! As we all know, even if the original ink is used, the color cast may appear more or less. This phenomenon is related to the brand model of the ink, the type of paper used to print the photo, and even the ambient temperature and climate during printing. relationship. However, as the printing technology continues to mature, printers introduced by many manufacturers can automatically correct the color cast phenomenon through their respective drivers. As long as you can make appropriate print parameter settings, you can make the printed photos with The real effect is infinitely close. Of course, if you notice a serious color cast during the printing process, you may want to check the printer's ink cartridge carefully to see if the ink has been exhausted; once you have found which color ink is used, Light should be replaced in a timely manner.

Error 6, the sublimation printer and inkjet printer have the same effect when printing photos

This statement is obviously wrong. When printing digital photos, inkjet printers often simulate the change of the color of digital photos by the size of the number of ink dots sprayed. However, due to the limited number of ink colors, ink dots themselves have no function of depth change, so no matter what How high the resolution of the ink printer is, and in the lighter shades of the photos, there are ink spots, so that the continuous tone of digital photos will not be reflected in lifelikeness.

The dye-sublimation printer heats and vaporizes the pigment on the ribbon, and then transfers the color to the photo paper. Because the temperature of the pigment vaporizes through the different heating temperatures, it often occurs when the color depth is expressed. Very realistic, so that sublimation printers can have a continuous and soft tone for every pixel. Therefore, from the effect of actual printing, the effect of thermal sublimation printers in printing digital photos is better than that of inkjet printers.
