![]() That boils down to an 8.5 x 11 print at full resolution without any loss of quality or resolution in the translation between screen and print. If you print at the native "photo quality" PPI of an Epson printer of 300ppi, you would end up with the following: Assuming you have an 8mp camera, your image sizes are likely to be around 3200 x 2400 or so. Screen/camera pixels do not directly translate to print pixels (PPI, pixels per inch), so you need to translate your image pixel size into a print size by dividing your screen pixel sizes by the PPI of your print. Keep in mind that the quality of a print is often more dependent on what is being printed than its size in megapixels, and even if your image size is not dense enough to mathematically fit onto a certain page size, you can still blow most images up pretty large without significant or noticable loss in quality. ![]() The optimal resolution you need for your product can be found by going to our website, hovering over the corresponding Product in the upper menu, and going to "Professional zone" in the submenu that shows up.There are some general rules you can use to determine the "maximum" (I use that term loosely) print size. The smaller the file, the faster the transfer! Then, send the compressed image(s) via our software or Online Shop to our specialist laboratory.Once you have finished editing your image, save it to a compressed file format (JPEG) to reduce the file size.This allows you to edit and modify your image without recompressing after each save, which could result in loss of detail. Save your image in a non-compressed file format (e.g., TIFF or Adobe PSD).Download the images from your digital camera (with the compressed standard file format supported by your camera).To avoid further detail loss, edit your images as follows: ![]() ![]() Any image compression will result in loss of detail, even if they are not visible to the naked eye. The file format when downloading images from the digital camera is usually JPEG (this file format is used because of the limited memory of the digital camera). The minimum resolution is 100 dpi (40 pixels/cm).Įdit images for optimal output quality The output quality depends on the image compression and the file formats of your images. For good output quality, you should use a resolution of 200 dpi (80 pixels/cm). At this high resolution, the files are larger than at a lower resolution. If you have a fast Internet connection, larger files are not a problem For excellent picture quality, you should use a resolution of 300-400 dpi (120 pixels/cm). A list of the respective production resolutions of our products can be found by going to our website, hovering over the corresponding Product in the upper menu, and going to "Professional zone" in the submenu that shows up. Optimal file resolution for high-quality prints The best file resolution is determined by the image details, the file size and the maximum possible resolution of the output device. Uncompressed files (e.g., TIFF or Photoshop PSD) can easily be converted to compressed files by simply storing them as JPEG files. These values do not lead to a visible loss of quality or detail. When using Adobe Photoshop, you can compress your images with a ratio of 8 or higher. Excessive compression (under 70) leads to a greatly reduced picture quality, especially for striking colors, such as red, as the result will be very noticeable. ![]() For an optimal quality, we recommend quality level 90. JPEG files To reduce the file size and increase the transfer speed, you can save your images as JPEG files. Learn more about colour spaces here: sRGB, Adobe RGB and ProPhoto RGB. RGB colour space For better results, you must attach your pictures in RGB colour space. However, in order to transfer your digital images as quickly as possible, we recommend using JPEG format as it significantly reduces image data. Saal Digital's software supports the popular file formats JPEG and PNG. Resolution, colour space and file formats for photo products ![]()
