As my projects on Instagram and Behance grew in popularity, there have been a lot of personal messages and requests to explain in a tutorial how to recreate the gradients used in them.
Risograph style, noisy gradients, spreckled gradients, I’ve searched it all but I couldn’t find a good, free tutorial that explains properly how to create this style in photoshop. So, here is my take on it.
One Example of how to use this technique (from 36 days of Type 2017).
In preparation of this tutorial I have been playing around with a few different techniques on how to create them in Adobe Photoshop CC 2017 (it should work the same in every version from CS3 upwards).
Bitmap Shading/Bitmap Gradients(2)
One of the coolest method that got a lot of steam in the last year is the use of the Bitmap color mode in Photoshop. There are many different possibilities you can it with, enough to warrant a tutorial on it’s own. For the sake of simplicity I will focus on one of the simpler ones, the one you see in that is more commonly used by Graphic Designers and Artists around the world.
1. Duplicate your layer into another image
For this step, you can either just use the individual gradient layer or the whole image with the «Apply Image» (image>apply image) function
2. Convert it to greyscale (image>mode>grayscale)
Photoshop will ask if you really want to do it if you have more than one layer because to convert it it will merge all layers together on one background layer.

3. Convert it into bitmap with Diffusion Dither (image>mode>bitmap)
There are a a lot of awesome options but for this tutorial we will use Diffusion Dither. Don’t be afraid to try out the other methods, there are a lot of cool options. You can even create your own texture to use! Now here is the tricky part: You will need to play around with the DPI of the image to get the desired effect. I usually just use a value around 60–75% of the original PPI of the image as it works best for the style I want to achieve. But as always experiment with it and see what works best for you!.
4. Resize the Bitmap image (image>image size)
This step is really simple. Just go to image size and resize it back to it’s original PPI (in this case I used 300). If you do this while still in bitmap mode Photoshop will keep the pixels with sharp edges, if you convert the image back before resizing it the pixels will blur a bit, giving a round effect if you play around with contrast after.

5. Take the layer back into the original file
Risograph-Like gradient effect with noise(3)
The Method I used in most of my 36 Days of Type Letters is a bit different than the first one. Here we will play around with the noise filter in photoshop.
1. Create a new project at least twice in size of your original image
If you want to add the effect on the whole image, choose at least twice the size of your artboard. If you simply want to apply it to one gradient you can just get the size of that and double it. It isn’t important to match the numbers exactly it just has to be a lot bigger than the original gradient. Twice usually fits well for me as you might run into problems with your computer performance really fast if you create huge images. Make sure the DPI of the new image matches up with your original image.
Make sure the noise is on full strength and monochromatic.
2. Apply noise on the new, bigger project
Use a white or black layer and apply the filter noise on full strength and make sure you have the Monochromatic box ticked. As always you can play around with the settings but those are the ones that work best for my personal workflow.
3. Copy the layer back onto your original file, scale it down and set it to overlay
This is a really important part as it will make or break the effect. Scale the layer down as much as possible while still covering all edges of your artboard or gradient. The whole trick in this workflow is using noise with bigger detail than the standard one.
Now that you’ve done that, set the Blend Mode to Overlay. Others will work too but I most often use that one.
4. Increase the contrast of your project/gradient
Now the only thing left to create this effect is increasing the contrast over the gradient by a very strong margin. I usually use Gradation Curves and just go crazy with them.
Voilà, there is your effect. I used it in a lot of images, particularly these ones:
Extra tips and tricks
I generally never use the standard noise but always create it first on a bigger image. It just gives a more crisp and detail look.
If you want to make the effect pop even more you can simply sharpen the final image (I like a combination of add image, smart objects and high pass for this)
It can be wise to only use this effect on the gradients themselves (which you should always have grouped in a layer by themselves) because the high contrast might make other elements of your project dissapear or generally look not so good.
If you want to use this effect with colorful shading you can always start with a black and white one, reduce all the effect layers to one gradient layer, select that and copy that selection into a new canal. After that, just click the canal while holding down and then you have a selection of the noisy gradient which can be used for any color layers you might have.
Create Spreckles with mezzotint(4)
This method is the easiest one but you also have the least control over it.
You simply use the mezzotint filter (Filters>Pixellate>Mezzotint). From there, play around with the settings to create your desired effect. I mostly use the setting “small dots”, however others could work too. As with the other methods, a good trick is to create a new, bigger image with the gradient on it, apply the filter there, move the layer back into your original file and resize it.
I hope these quick methods helped you, let me know if there are any questions! I would love to see the cool designs you came up with using these methods. Post them in the comments or send them to me directly via mail
