How to make a basic watermark in Photoshop

1. Starting

• Open a new document:
• Size: 900 x 600 pixels

2. Text Sizing (Signature)

• (optional) If you’d like to make an Action (Alt + F9) then start recording now:

• Begin by creating a text box with the settings as shown:
• My text is ‘©m.scott’ in Mistral, BOLD, Italic:
• ‘©’ size: 24 pt: (copy my © symbol!)

• ‘m’ size: 60 pt:

• ‘.’ size: 60 pt and width 75%:

• ‘sco’ size: 60 pt:

• ‘tt’ size: 60 pt and height 81%:

3. Text (Website)

• Now place a text box below your ‘signature’ (same width):
• Use a font that is all capitals or simply type in capitals – I’m using Copperplate Gothic light, BOLD, Italic:
• Text size: 12 pt:
• I’m using a black layer (separate) temporarily to see my text and layout!

4.a. Saving as .PNG and Applying Watermark

• You can save it as a JPEG, GIF, PNG anything, however I think PNG is best for quality – doesn’t degrade the data.
• Simply save this as a PNG!
• When you want to apply your watermark on an image, open it in Photoshop and go, Right Click (on layer) –> Duplicate Layer… and select the Document!
• To scale your watermark go, Edit –> Transform –> Scale (hold Shift to keep aspect ratio).
• Don’t forget to readjust the Opacity – 50% is usually what I apply.

4.b. Defining as a Brush

• For quick applications of your watermark you can save it as a brush go, Edit –> Define Brush Preset!
• BUT, you must invert (Ctrl/Cmd + I) your watermark first otherwise you’ll get an error message, because the brush preset interprets the white as transparent.
• If you do not like the black watermark then you just invert it again in your image once applied!
