Creating blinking text in Photoshop can be simple. The most common method is to use a GIF file. GIFs are the standard for simple animation images for the web. To create a blink effect, we'll create multiple frames of the same image and then remove the text for about half of them. The removed text will appear to flash on and off again when the sequence loops. Animation cannot be used with JPEG files, which are for static images only.
Create a new document in Photoshop by selecting "New" from the "File" menu at the top of the program. Specify the image dimensions and other settings to your preferences. For a basic document, a 200-pixel square in RGB mode with a white background should be sufficient.
Create a new layer by clicking the "Add New Layer" button, which looks like a turning page, in the "Layers" panel. If the layers panel is not visible, select "Layers" from the "Window" menu at the top.
Select the text tool, which looks like a capital "T" in the toolbar. Click and drag on the stage to create a text area, then type the text you wish to make blink.
Open the "Animation" panel under the "Window" option of the menu at the top of the program.
Click the first frame, then click the "Duplicate Selected Frames" button at the bottom. The icon looks like a page turning.
Select the new frame, then select the layer with the text you created. Click the "Layer Visibility" button next to the layer to turn it off. The icon looks like an eye.
Return to the animation panel and duplicate the frames with or without the text to lengthen the duration of the blink or the on/off ratio. You can use the play and pause buttons to preview the image.
Click the "Save for Web" option in the "File" menu. Change the file type to GIF and adjust the loop options to "Forever" or "Once," depending on your preference.
Click "OK" to export. To see your image, open the file in an Internet browser.
Later editions of Photoshop can export video files instead of GIFs. To do so, click "Render Video" from the "Export" option from the "File" menu.
