About this deal

Next, divide the number of pixels in the height of the file by 200. (1600/200=8). So, there you have it. A file size of 2,000 pixels X 1600 pixels can be printed to make a good quality 10 X 8 photo when printed at 200 DPI. When a printer prints at 300 dpi, it spaces the pixels onto paper at 300 pixels per inch of paper. Printing 3000 pixels at 300 dpi prints a 10 inch image on paper. We generally always want to print photos at 300 dpi as best choice. And in our 4x6 to 5x7 example, if matching the short sides, the two before and after sizes compare as 4 to 5, which is 5/4 = 1.25, which is 1.25x or 125% enlargement in the copy. Note that matching the long sides is 7/6 which is 1.17x, a different enlargement number (because the shapes are different).

If printing yourself at home, the Print menu in your photo editor normally does use the file's scaled image dpi number (pixels per inch) to size the images on paper (regardless if it matches the paper size at all). But it typically will also allow changing that dpi, called scaling (to fit the paper size). For example, if an image dimension is 3000 pixels, then specifying that file number as 300 dpi printing resolution will print it to be 3000/300 = 10 inches print size (even if the paper is only 4x6). But the dpi number that your digital camera initially stores in the image file, unless you have reset it to your planned value, is otherwise far from meaningful, it is just some arbitrary number, which will print SOME size, but not likely to be your own printing goal. Hopefully, you have already properly scaled the image for your selected paper size. Video monitors: Video does not use dpi, but scanners do. The calculator shows that if you scan a 6×4 inch print at 100 dpi, it will create a 600×400 pixel image, and the monitor will show it at that same 600×400 pixel size. Scanning to print a copy at the same size is a very common goal. It's important to realize that an area scanned at 300 dpi will create the pixels necessary to also print the same size at 300 dpi. The concept either way is pixels per inch. And 300 dpi is likely what you want for a photo copy job. The one-hour print shops accept larger images, but many machines are set to use 250 dpi. You may think that the job is done already but the print is the final part of the workflow (share) and is as every bit important as the previous four stages:So scan and then for printing preparation, FIRST crop to paper shape. Crop as desired to both fit paper shape and also to adjust crop size and location to improve artistic composition — keep important detail, and crop away only the unimportant - Duh. 😊 But it is a choice that you can make while you are seeing it. You can make this crop be the best size on the image, and placed at the best location, but the shape will be fixed, matching the declared print shape. Then SECOND, resample that cropped image to be the smaller desired size to print (pixels, for example 3000 pixels for 10 inches at 300 dpi). Cropping to match paper shape is normally about trivial to do (see procedure). We must choose this ourself. All images have been cropped to standard aspect ratios, OR you have calculated the dimensions for each image size and mount size with cut-out/window. If the Result text might not be meaningful yet, then start at this: Cropping, Resampling, Scaling. It's the basics of something we all need to know about printing images. The idea is not to simply compute some numbers, but to try to explain how you can already know this yourself. It's actually pretty simple. I recommend (without any commission or prejudice) One Vision Imaging Limited for all my fine art prints. The print quality and production are always first class and they have excellent customer service so will be more than happy to help you through the process if my guide is beyond what you can process easily. Scanner mechanisms use a sensor with a single row of maximum resolution pixels across the width of the bed (lesser resolutions are resamapled, for which even powers of two are much less complex and considered preferable), and a carriage stepping motor to move that one pixel row down the height of the image. A common procedure that the meticulous users use is instead of entering some precise but non-standard scanning resolution (like maybe 1548 dpi), is to instead intentionally scan a little larger using a next larger standard scanner resolution menu choice, from the scanner menu (offering the powers of two). Perhaps that next one is 2400 dpi, but the next standard step at 100% scale is sufficient. Unnecessarily even larger is not a plus (at least not for this one specific goal). Extra pixels also allow a bit tighter artistic crop, which is often a good thing anyway. And resampling in the photo editor has ALL pixels available, instead of a single row. And it is normally necessary to first crop to match paper shape. The procedure for printing is: First crop to paper shape, and then resample smaller to proper size for printing at about 300 dpi.

But that is just a choice, and the difference is small, and it will be difficult to realize a difference from scanning at 1548 dpi. There is another different mild compromise which is reasonable at times. For example, at the calculators initial defaults above (scanning 35 mm film to print on 8x10 paper), Button 2 at 300 dpi computes to scan at 2540 dpi. Which is close to 2400, so instead of increasing to 4800 dpi, try Button 3 at 2400 dpi, which computes printing at 283 dpi, which should be very acceptable. You'll never see the difference from 300 dpi, and the local one hour lab probably prints at 250 dpi anyway. The negative is comparable to the composer's score and the print to its performance. Each performance differs in subtle ways.” Ansel Adams Either way, it is good if your plan properly prepares the image for printing. Sufficient pixels is important, but first cropping the image so that the image SHAPE actually matches the selected paper SHAPE is also a very important concern. Different paper sizes are different shape. And we need to provide the necessary pixels. The simple calculation for that acceptable image size for printing is: So either way, you still must prepare the mage for printing. An example of a universal numerical method of scaling (and very easy):

A possible green text suggestion in the scanning options: The computed scan resolution for film possibly can result as like 2540 dpi, closely missing one of the scanners default multiples of 300, 600, 1200, 2400, 4800 dpi. It will show and use that number, but if the miss is pretty close and might be considered negligible, the calculator might also suggest for example, that scanning at 2400 dpi (instead of 2540) would still print the same size at perhaps 283 dpi, which likely cannot be distinguished from 300 dpi (see more below). Many one hour labs limit printing to 250 dpi anyway (but their continuous tone is better quality than an inkjets dithered reproduction). Again, it is just an alternate suggestion to be aware and possibly consider. You can also get the same information for different multiples in Option 3 by just trying a couple of values of available resolution.
