I’m going to teach you how I made this cardboard.

I’ll start by saying there are probably easier and other ways to do it, but since nobody else is sharing how to I started playing around to see if I could figure out how to make something that looked like corrugated cardboard. This is what I came up with and hope somebody else finds this useful.
Step 1. Make a new canvas (document) sized at 12 inches by 12 inches and 300 resolution (will also work fine at 200 resolution and I generally design at 200 resolution, but if you are designing professionally standards are 300 resolution). Set your foreground color to #856543 and your background color to #e2b379. Fill your background layer with your foreground color. Go to Filter > Sketch > Halftone Pattern. Choose line and then use the following settings size 12, contrast 19.

Double click on your background layer to unlock it and then go to Edit > Transform > Rotate 90° CW to flip your stripes to vertical instead of horizontal. Your file should now look like this.

Step 2. Go to filter add noise and add 26% noise set to uniform and monochromatic.

Step 3. Go to filter > Unsharpen mask and set your unsharpen mask to Amount: 500 Radius: 250, Threshhold: 100

Your cardboard should now look like this.

Step 4. Go to filter > stylize > diffuse > Darken only repeat this 2 more times (for a total of 3 times)

Your cardboard should now look like this.

Step 5. Go to filter > texture> grain and switch to vertical with these settings intensity: 40, contrast: 0

Your cardboard should now look like this.

I could have stopped here, but I wanted to have a little more depth so added the following.
Step 6. Duplicate your layer and with the top layer go to emboss set it to the following Angle: -130, Height 15, Amount:500. Don’t worry about the blueish coloring, we’ll fix that in the next step.

Step 7. Desaturate your top layer and change the blending mode to soft light.

Step 8. Merge your two layers and your finished cardboard will look like this.

Here’s an example of what you can do with it. I find the cardboard looks best used underneath something.




I normally set my unsharpen mask at Amount: 50, Radius: 5, Threshhold: 0. Sometimes I go higher and sometimes lower, but that’s a good place to start. There are a few pictures that I won’t use the unsharpen mask on, but not many.
