How to enlarge digital photo printing

Most readers and friends would like to enlarge the prints they like. Although you can use special printing software to enlarge the print. However, the vast majority of printers have the function of split printing. With this function, large pictures can be printed and put together. For example, with the Epson PM-830C, it is possible to enlarge and print 2×2, 3×3, and 4×4 images in vertical and horizontal directions.

Although the A3 format printer has also been reduced to the right price, if you use an ordinary A4 format printer for split printing, you can print a much larger image than the A3 format. The order of split printing is roughly as follows:

(1) In the print setting screen of the image processing software, the photo to be printed is set so that it can be printed on one A4 page. If possible, it is best to change the resolution setting;
(2) Click the Print button to open the printer driver window and set it to split printing;
(3) The image is printed on several sheets of A4 paper, the photo parts are cut with a cutter, and then the photos are perfectly glued together on the back.

The following describes in detail the settings required to print the image on a sheet of paper and the settings of the printer driver. The printer is PM-830C and the software uses Photoshop Elements (Adobe systems).

▲ Images with 2×2 aspect ratios are glued together and images with blank borders are printed on A4 paper. Intuitively speaking, when the image looks large, even a poorly-performed photo will feel immersive.

The first is to set the size needed to print the image exactly on one sheet of paper. In Photoshop Elements, select "Image" → "Change Size" → "Image Resolution", and then set the print size in the Open Image Resolution window.

In order not to degrade the image quality as much as possible, the selection of "image resampling" should be canceled. This allows you to change only the print size without changing the size of the original data. Then specify the file size (up to 29.7cm x 21cm) required to print the image to a A4 size.

â–² The "Image Resolution" setting window just opened. In this window you can change the pixel size and file size at the same time

â–² Cancel the "Image Resampling" option and change the file size. Without changing the number of pixels in an image, it is possible to change only the image size at the time of printing. In order to print to A4 printing paper, it is necessary to enter 21cm in the height column. This page setup is completed, and the image can be printed on A4 format printing paper. Next, it is the printer driver setting in (2).

In the driver window, you can set the paper size, paper type (photo special paper or copy paper, etc.) and portrait or landscape orientation.

In Photoshop Elements, first select "File" → "Print" to bring up the print window, then select "Print Settings" and select "Properties" in the Page Setup screen to bring up the printer driver window.

Set the paper type and print orientation in this window. Of course, you also need to set the required split print. Incidentally, unlike split printing, there is also a print method that can print 2 or 4 identical contents on a single print sheet. Whenever you want to print out the WPC ARENA report, you can print 2 pages on a single sheet of paper when you read it carefully. It's easy to carry half a sheet of paper with you. Readers can try this printing method.

â–² Open the Print Settings window by selecting the "Print" command in the "File" menu in Photoshop Elements. In this window, you can only click on the "Print Settings" button since you can only make simple settings.

â–² Click the "Print Settings" button to open the window. Then click the "Properties" button, you can open the printer driver window

â–² The picture shows the Epson "PM-830C" printer driver screen. Under normal circumstances, after selecting the "type of paper" correctly, it will print very good results. This time, because it is to be printed on photo special paper, first select "PM Photo Paper"

â–² Select "Page Setup" tab, because the printed photos are horizontally oriented, so choose landscape printing

▲ The key settings for this printing are here. Select the "Layout" tab, then click the "Layout/Poster" option. Select "Poster" again. Since we need to print 2×2 total 4 pages this time, we choose 4 pages next. If you select "Layout" instead of "Poster", you can choose to print 2 pages or 4 pages on 1 sheet of paper

â–² It is printed. The only work left is to use a cutter to carefully trim the borders and stick them from the back with tape. By the way, if you use a paper cutter and a metal ruler to cut it, it will not only be simple but also effective. Because the photos are relatively large, they will be far away when they are enjoying. Therefore, using this method, unexpected and good results will be obtained.
