Adjust photo quality in Photoshop and prepare for printing in the best possible way

Digital printing requires 120ppi – the number of pixels per inch – for good print quality. Most digital printers also have motors that convert color – RGB Red Green Blue – to CMYK – Cyan Magenta Yellow Black – cyan, magenta, yellow and black.

Photo quality in Photoshop. Commercial prints require higher resolution, and RGB images usually need to be converted to CMYK or black and white. The minimum resolution is usually 300ppi at 100%.

 For best print quality, images should not be artificially enlarged to more than 110% of their normal size in Photoshop. To prepare images with Photoshop for printing, do the following:

1. First, open the photo you want. We are using a 8.75 x x 8.75 ع image.

2. Check the appropriate resolution and size of the photo by going to Image> Image Size. Click Cancel to close the dialog box.

3. Select the Crop Tool.

Then go to the options Bar and select Size & Rotation, enter the length and width values ​​- width and height – for both – 9 and set the resolution to 300, then ok, as shown below:

4- Go to the image and specify the cutting range. Here we put the flower in the middle of the photo. Then press Enter to cut.


5. Select the Move Tool.

6. In the view menu, go to the Application Bar and select show rulers.

7. Go to the horizontal ruler at the top of the photo window. Hold and hold the slit area and drag down the guide down to the 8,875 position.

8. Go to the vertical ruler on the left side of the photo window. Drag and hold on the gap area – to position – 8,875 ”

9. Return to the horizontal ruler and drag another guide line – to the 8.5 ”position.

10. Go to the vertical ruler and drag again – to the 8.5 ”position.

11- Go back to the vertical ruler and drag a guide – until the sign 5 – and the final horizontal guide – until the sign 5.75 “-

12. Go to the layer panel and create a new layer.

13. Select the Rectangular Marquee Tool.

And create an area between the external guide.

14. Go to Edit> Fill. From the use menu, select white, make sure Preserve Transparency is not checked and click ok.

15. In the layer panel, set the opacity to 60.

16. Press Ctrl + D -PC- / Command + D -Mac- to deselect the range. Save your work and keep the file open.

17. TIFF format requested. Go to the Layer panel and click on the panel menu and select the flatten image.


18. The photo must be converted to CMYK for printing. There are many CMYK features to choose from. There are 4 separate categories. Web and sheetfed refer to the type of printer used. Coated and uncoated also refer to the paper on which the print is taken. In this example we use web coated. Go to Edit> Convert to Profile. 

In the dialog box, select Working CMYK – US Web Coated (SWOP) v2 from the Profile menu and then ok:

19. Go to File> Save As and rename the file and select and save the TIFF format from the menu.

20. In TIFF Options, leave the settings in the default state and click ok.

21. Close the TIFF file. If you have to resize the Ghosted box, you can reopen the original file, remove the layer from the box, and do it again. No need to go back to the crop image.
