1. Create a new document with the following settings:
Create a new document specifying your desired height and width(minmum 600 px wide). Make sure the resolution is 72 pixels per inch and choose RGB color mode. For our example we are using a 4x3 aspect ratio which is the size we use for our eCard/invitation designs.
2. Filling the background
Fill the background layer of the image with a gradient, a solid color, or an image. Try to pick a background that works well with your overall design, and is not too busy.
3. Paste in your logo
Insert your logo by copying and pasting or create a new one
4. Add your text message
Use the type tool to add your message.
Tip: Make a list of all the messages you want to create, and type them all in one session, as separate layers. Then you can create multiple eCards from the same file. (Example: Thank you, Special Announcement, Special Event etc.)
5. Dress it up!
Add a drop shadow and outer glow to your logo or text for added style.
6. Save the file at the proper size and image quality
Save your original design as a Photoshop file (.PSD) as you usually do. This way you can quickly make more eCards/invitations from your template as your needs dictate.
To save your design in the format needed for an eCard/invitation, select "File > Save for Web and Devices" from the Adobe Photoshop menu. In this example, we chose the JPEG file format (which works better than .GIF if your image contains smooth gradients — .GIF files work best with solid colors). Adjust the quality to find the best compromise between small file size and clear image. Smaller files will load and display quicker for you and your eCard/invitation recipients.
Save this file where you will easily remember where it is located and then follow the instructions for how to upload your eCard/invitation design.
