\n\n 300 dpi vs 600 dpi
As a good rule of thumb, high-resolution images are those with 300 DPI and a large pixel dimension. Also note that what is considered a high-quality image depends on the desired result. In some instances, an image 400 or 600 DPI may be needed. To learn more about high-resolution images, check out this article. 2. Key Features. Prints and encodes RFID labels and tags. Maximum Print Width - 4.09 in./104 mm. Available Print Resolution - 203 dpi/8 dots per mm, 300 dpi/12 dots per mm, 600 dpi/24 dots per mm. Maximum Print Speed - 14 ips/356 mm per second (203 dpi), 12 ips/305 mm per second (300 dpi), 6 ips/152 mm per second (600 dpi)

The higher the DPI, the more detail and sharpness your print will have. However, DPI is not the same as PPI, or pixels per inch, which is the measure of the resolution of a digital image. PPI

72 DPI for everything for screen (sometimes 75 DPI too). This way, the printed version of this image will be crappy or small. Useful if you want to protect your images. 150 DPI for print of small quality (demos for future prints, website etc for clients) 300 DPI (to 450) for nice quality print without high res.
If you want files that are easier to work with, 300 DPI scans would be a better choice. 600 DPI Scans Allow for Double the Enlargement Part of the benefit of scanning your old photos, in addition to the added security of backing them up in a digital format, is the ability to create new prints, enlargements and photo products such as photo books.
For example, a 300 x 600 dpi means the ID card printer will deliver 300 dots per inch of width and 600 dots per inch of length. Alternatively, a resolution with just one complete number i.e. 300 dpi means the printer will deliver 300 dots per inch of length and also 300 dots per inch of width. Which printers offer a better print resolution?
Video monitor specifications have no associated dpi number, and screens will simply show higher resolution scans as larger images (chapter 5). For example, there is no way you can fill a 800x600 pixel screen from a 6x4 inch photo if scanning at 72 dpi. It requires about 150 dpi. You will only get 432 x 288 pixels if scanning 6x4 inches at 72
You need to supply one more fact: what size will the print be. You can create a new file in photoshop and work everything out. Example 11 inches x 15 inches RGB image area @ 240 dpi = 27.2 megapixels image file.
So, a 300 ppi save as PNG from Photoshop would embed a value of 11811 ppm (pixels per metre). When Photoshop opens a PNG with this resolution metadata, it performs an “on the fly translation” from PPM to PPI: 118.11 x 2.54 = 299.9994 ppi rounded up this is 300 ppi. Upvote. That said, Pixlr Editor contains many graphic design tools that will work just fine for you, and Pixlr for Mac and PC can handle large, high resolution files. As with most things in life, the quality of output depends on the quality of input. Start with the highest resolution or largest images you can to get the best results. The resolution setting maps an image’s pixel dimensions to its physical size. With a pixel dimension of 600 x 600 and a resolution of 300 DPI, the image has a physical size of 2” x2”. The resolution setting is crucial when you want to print. A 1600 pixel x 1200 pixel image printed at 72 ppi, for example, would output at over 22” x 16”. Epson WorkForce ES-200 Portable Duplex Document Scanner with ADF. Manufacturer part B11B241201. Dell part AA864993. ★★★★★ ★★★★★ 4.5 (23) Estimated Value. $239.99. If you want files that are easier to work with, 300 DPI scans would be a better choice. And if you are just uploading to social media for sharing 150 DPI is often fine. For the lowest quality resolution choose 72 dpi. 600 DPI Scans Allow for Double the Enlargement Good results for printing yields 300 DPI, but it is better to apply 600 DPI. The DPI for the image to be printed is largely dependent on the printer (or plotter) on which it is printed. There are printers and plotters with a resolution of 2400 DPI or more. Next, the DPI you choose is highly dependent on how you intend to use the image. I'd rather have a 800 DPI JPEG file than a 400 DPI TIFF. What you saw is correct, that 600 dpi jpeg would certainly provide a significantly better scan than the 400. For prints, I wouldn't even bother with TIFF. The chances of you doing post production on them is minimal at best, so having a tiff file of them is mostly unnecessary. For example, sending a 203 DPI format to a 300 DPI printer will result in an image that is approximately 33% smaller. Solution. Verify the printhead resolution is the same on both printers by comparing a printer setup label (Configuration Label). Note the line that states the Resolution value. These should be the same on both printers.

Page 2: 75, 300, 600 Dpi Page 3: 1200, 2400, 3200 Dpi, Color Rendering Indeed, at 600 dpi it's hard to make sweeping comparisons regarding quality. The multifunctional Epson scanner is,

The 300/600 etc is mistakenly referred to as DPI but is actually PPI, pixels per inch. This is an input setting that is tied to the density of pixels in the image data and is strictly relevant to print size in inches. 300 PPI is traditionally viewed as a rubric, but larger prints can be output nicely at 240PPI.
