What are the skills for printing photos?

First, choose a good photo. Please don't blame your printer if your source image can't print the effect of a real photo. It is not enough for a photo to look good on the screen. To choose a good photo, we need to consider the following factors: 1, and the pixel of the camera is the key. At present, some people have a misunderstanding in the use of digital cameras, thinking that as long as the pixels are higher, the quality of the photos taken will be better. Actually, it is not. How many pixel values are used to shoot mainly depends on how many sizes of photos will be printed in the future. The average family does not intend to print large-size photos. It is equivalent to a setting of about 2-3 million pixels, and it is enough to print 5-6 inch photos. If you just want to upload to the Internet, you can use a smaller setting. Of course, if you are engaged in photography, you may occasionally get a good photo and plan to take part in a competition or print a large-size photo. Of course, try to use the maximum pixel setting when shooting. 2. Resolution is very important. The standard measure of photo clarity is dots per inch, or dpi. You should also ensure that: for small photos (4×6 or lower), the electronic file of photos should have at least 240 dpi resolution; For larger photos (5×7 or higher), the resolution should be at least 300 dpi. 3. Format the file. Even if the photo resolution is high, it needs to be saved in the correct format-TIFF or JPEG format. For best printing, always save photos in TIFF format. Although this format is slightly larger than other formats, it is the most reliable. JPEG format is the best choice for sending photos by email. 4. Quality control. To retouch the original photos, you should first check the images, visually check each image, and perhaps write some notes. Is this image too big, too dark, too bright or too fuzzy? After picking out the faults, use image processing software to improve the final image effect and correct one problem at a time. Of course, not every photo needs so much work. However, almost every photo needs targeted adjustment. You can try many things until you get a satisfactory image and then save it. Digital image adjustment requires mastering image processing software, such as Photoshop, UleadImpact, Photo-Deluxe, etc. Then consider what to do next. For example, don't use a wide range of effective settings and don't make too many changes; Do only a few small gradients at a time, preview the effect first, slowly achieve the best effect, and then be sure to save it. Secondly, choose a good printer and learn to use it. You will learn the basic knowledge about printer selection and the skills of how to make full use of printers to get the best printing results. 5, DPI problem. The printer shall have at least four colors and the resolution shall be at least 600×600 dpi. Otherwise, the printed photos will be pixelated, which means they will have jagged edges. (HP printers can provide resolutions as high as 2400× 1200 dpi-advanced photographic paper is required. 6. Driver settings. Your printer should use the latest version of the driver. Make sure that the parameter is set to the highest print quality. In addition, try all the options provided by the printer driver-sometimes, you may find that some variables, such as advanced color settings, help to improve the printing effect. 7. Printer resolution setting. Print at an output resolution of 240 to 300 dpi. This is a reliable guarantee to get the highest quality photos. 8. Paper settings. Make sure that the selected printing paper is set correctly. For example, "photographic paper". Generally, the paper setting can control the amount of ink output to the paper. For example, the Plain Paper setting uses the most ink, while the Glossy Projection Film and Photographic Paper settings use the least ink. When you find a setting that is very suitable for a specific paper type, you can save it and give it a name that you can remember. 9, clean, clean. Please clean your printer at any time so that it can work at the highest efficiency. 10, paper selection Although the common copier is readily available, it is not suitable for photo printing-it usually causes the printed results to be unclear or not bright. If you use photographic paper specially designed for your printer, the printing effect will be the best. For example, when the printer prints at the highest speed, not all non-HP paper can use HP ink. Be sure to test different types of paper before buying a lot of paper. 1 1, drying time, be sure to leave enough time to dry before you frame the photos or put them in the scrapbook. The drying time of most HP inks and papers is about one hour, but-due to the specific environment at home or office, such as temperature, direct light and humidity, the drying time is often affected. If the photo touches something, such as the glass on the photo frame, it will be safer to dry the printed photo for 24 hours. 12. If you want to print multiple photos, the best way is to take them out of the printer and put them away. This will prevent the photos from getting dirty or falling to the ground.
