Vintage Letterpress Effect

In this GIMP 2.8 tutorial you will learn a quick and easy way to give your typography an ink-stamp-style effect that originated from the old letterpress printing technique.

Letterpress printing is a technique of relief printing using a printing press.Movable type is composed and locked into the bed of a press, inked, and pressed against paper to transfer the ink from the type.

This can result in some texturing, especially if some areas of the printing surface receive little or no ink. Back in the day, this would be seen as a flaw in the print, but now we try to fake this kind of texturing to simulate an aged and nostalgic appearance.

The letterpress effect is created from a texture file. The texture can be anything with plenty of fine grainy detail. Concrete, rust, or grunge textures all work well. For this exercise, I used a rusty metal texture that can be downloaded free from Image*After.

Desaturate the Texture, Colors - Desaturate…, Choose shade of gray based on Lightness. Open the Levels dialog, Colors - Levels…, and use the slider handles to increase the contrast of the image (80, 0.70, 208). Try to generate harsh white details that will represent the paper showing through the ink.

I used the Text Tool to create a layer of text, then added a mask to that layer, Layer - Mask - Add Layer Mask… .

Select all of the Texture layer, Select - All (or ⌘+A), then copy the selection, Edit-Copy (or ⌘+C). You can now hide or delete the Texture layer.

Then right-click the Layer Mask’s little thumbnail in the Layers pallet to make it the target. Paste the copied texture into the layer mask, Edit - Paste (or ⌘+V),  then anchor the layer to the mask, Layer - Anchor Layer (or ⌘+H).

The texture has now been applied as a mask and is rendering black areas of the mask transparent and white areas opaque. Adding a background layer of a solid color will show the effect more clearly. If too much of the text is currently being erased, as is the case here, inverting the colors may result in a better effect, Colors - Invert.

Finally, I added an old paper texture layer to enhance the effect, File - Open As Layers… .

The final effect gives the text a popular vintage look by simulating the pressed ink appearance of those old letterpress prints.

This tutorial was derived from a Photoshop tutorial by Chris Spooner.

Color Sensitive Text

In this GIMP tutorial you will see how to make the color of text alternate between light or dark depending on the background. I developed this procedure to meet the needs of someone who follows this blog and made a request for help. I hope others among you will find it useful, too.

Open the background image.

Duplicate the background layer, Layer- Duplicate Layer. Desaturate the background layer copy, Colors - Desaturate... by Luminosity.

Apply the threshold filter to the background layer copy, Colors - Threshold…, push the slider to the right until there's hardly any white bits in the black.

With the Brush Tool, paint out any details to match the dominant color, black or white.

With the Text Tool create your text layer in black or whatever dark color you want to use. Position it with the Move Tool. Expand the text layer to the image size, Layer - Layer to Image Size.

Make the text layer invisible by clicking the 'eye' icon in the Layers pallet.

Make the black and white layer active by clicking it in the Layers pallet. With the Select by Color Tool in Replace the current selection mode, click anywhere in the black.

Make the text layer visible and active. With the Select by Color Tool in Intersect with the current selection mode, click anywhere in the text. You should now have the portion of text that overlays the darker buildings selected. Make the black and white layer invisible.

Create a new transparent layer, Layer - New Layer..., on top of all the others and name it Light Text. Now, fill the selection on the Light Text layer with white or whatever light color you choose, Edit - Fill with BG Color. Deselect, Select - None.

Building a Spy Movie Banner

In this GIMP project, you will learn the basics of creating a movie banner in a style that might be used for a spy movie. You will use layer blending modes, text layers, and color manipulations, as well as other skills.

Source images you can download or use your own similar images:
Kremlin (Original photo by Yaroslav Ushakov)
Man in Suit  (Original photo by Rubén B. Todos)
Bull’s Eye

• Part 1. The Kremlin

Apply a dark, monochromatic red, slightly blurry effect to the Kremlin image.

Open the Kremlin source image. Convert it to grayscale, Colors -Desaturate..., Choose Shade of gray based on: Luminosity.



Duplicate the layer, Layer - Duplicate Layer. Set the blending Mode of the copy layer to Multiply and slide the opacity down to 70%.



Merge these layers into one, Layer - Merge Down. Name the new layer, Kremlin.

Apply a slight Gaussian blur with a radius of 5 for both Horizontal and Vertical, Filters - Blur - Gaussian Blur... .

Now, for the dark red hue. From the Colors menu, click Colorize... . Set the Hue slider to 360, Saturation 50, Lightness -15.



You can now set this image aside for a bit.

• Part 2. The Man in the Suit

Open the Man in Suit image. With the Crop Tool, remove most of the background area. Now add transparency (an alpha channel) to the image, Layer - Transparency - Add Alpha Channel.

You need to remove the remaining white background. The Select by Color Tool will do the heavy lifting here. Click and drag in the background until all that remains is to clean up the detail around the edges of the man. Toggle on Quick Mask mode, zoom in and, with the Paintbrush Tool, clean up any remaining bits of the background, especially in the hair and inside the man's right elbow. Grow the selection by 1 px, Select - Grow. Then clear the contents of the selection, Edit - Clear. Save the image and close.



You can now reopen the Kremlin background image. Open the Man in Suit image you just worked on as a new layer, File - Open as Layers... . Be sure that in the Layers pallet it is above the Kremlin layer and name it Man.Use the Move Tool to position the Man layer to the left side of the picture and down just a bit.

• Part 3. The Text

Add the movie title and some other bits of text to the banner. Select the Text Tool. For the title choose an appropriate font and size.  I used HeadlineA, 240 pt, Color white. Click in the picture and type the desired text. Position the text in a good place.



Create a selection around the text with the Select by Color Tool. Click anywhere on the white text and it will all be selected. Create a new transparent layer on top of all the others, Stroke. Reset the color swatches to the default. Apply a 4 pixel black stroke to the selection on the Stroke layer Edit - Stroke Selection... . Merge the Stroke layer down onto the text layer.



Similarly add additional text elements to the picture.

• Part 4. The Bull’s Eye

Open the Bull's Eye image as a new layer under the Spy Movie text layer. Set the blending Mode to Lighten Only. Reduce the Opacity to about 85%. Position the bull's eye where you like with the Move Tool.



You've now brought all the components together. Use this lesson as a starting point for your creative expression. Modify and experiment to your heart's delight!

Carve the Text

In this quick, fairly simple GIMP project, you will create the effect of text having been carved into a textured surface using layers.

Some techniques you will use in this project:

Layers

Text layers

Merging layers

Selection by color

Alpha channels

Noise generator

Gaussian blur

Open a texture image as the Background layer. I used a marble texture that I downloaded from Image*Afterhere. Select the Text Tool and create a text layer with your desired text and center it. Use a bigger, bolder font. I chose Futura Ultra-Bold Condensed, 196 pt.

Create a new empty layer, Layer > New Layer…, name it Gray. Use the Bucket Fill Tool to fill it with a medium grayish-pink color. Drag it under the Background layer in the Layers pallet.

With the Text layer active, make a selection of the text. Use the Select by Color Tool and click on the text.

Hide the Text layer by unchecking its ‘eye’ icon in the Layers pallet. Select the Background layer and add transparency to it, Layer > Transparency > Add Alpha Channel. Clear the selection, Edit > Clear. The Gray layer should now be showing through the text.

Add a new layer, named Black. Invert the selection, Edit > Invert Selection. Reset the color swatches to their defaults, and fill the Black layer with black, Edit > Fill with FG Color.

Duplicate the Black layer, Layer > Duplicate Layer. Name the copy White. Fill the White layer with default white, Edit > Fill with BG Color.

Deselect all, Select > None.
With the White layer selected, choose the Move Tool, slide the White layer up slightly, one or two pixels.
Do the same with the Black layer, except move it straight down. (Note: I have exaggerated this a bit for clarity.)
Select whichever of the Black layer or the White layer is on top, then merge them together into one layer, Layer > Merge Down. Name the merged layer Shadow.

Apply a slight Gaussian blur with a radius of about 3.5 pixels to the Shadow layer, Filters > Blur > Gaussian Blur… . Drag the Shadow layer between the Background layer and the Gray layer.

Finally, add a little texture to the carved surface within the letters.
Select the Gray layer. Add some noise, Filters > Noise > Noise Generator. In the  dialog, click the Poisson tab, 1 Photon, Luminance noise only is checked, Gamma correction is not checked.

Apply a Gaussian blur with a radius of 2 pixels.

To extend the project, you might like to use the original textured background instead of the Gray layer. Make some slight brightness adjustments and apply a little blur.
