Chapter 19: Type
Creating type 
About type 
Type in Photoshop consists of mathematically defined shapes that describe the letters, numbers, and symbols of a 
typeface. Many typefaces are available in more than one format, the most common formats being Type 1 (also called 
PostScript fonts), TrueType, OpenType, New CID, and CID nonprotected (Japanese only). 
When you add type to an image, the characters are composed of pixels and have the same resolution as the image 
file—when you zoom in on characters you see jagged edges. However, Photoshop and ImageReady preserve the 
vector-based type outlines and use them when you scale or resize type, save a PDF or EPS file, or print the image to 
a PostScript printer. As a result, it’s possible to produce type with crisp, resolution-independent edges. 
There are three ways to create type: at a point, inside a paragraph, and, in Photoshop, along a path. 
Point type is a horizontal or vertical line of text that begins where you click in the image. Entering text at a point 
is a useful way to add a few words to your image. 
Paragraph type uses boundaries to control the flow of characters, either horizontally or vertically. Entering text this 
way is useful when you want to create one or more paragraphs, such as for a brochure. 
Type entered as point type (top) and in a bounding box (bottom) 
(Photoshop) Type on a path flows along the edge of an open or a closed path. When you enter text horizontally, 
the characters are parallel to the baseline. When you enter text vertically, the characters are perpendicular to the 
baseline. In either case, the text flows in the direction in which points were added to the path. 
If you enter more text that can fit within a paragraph boundary or (in Photoshop) along a path, a small box or circle 
containing a plus symbol (+) appears in place of a handle at the corner of the boundary or anchor point at the end 
of the path. 
When you create type, a new type layer is added to the Layers palette. In Photoshop, you can also create a selection 
border in the shape of the type. 
Important: In Photoshop, a type layer is not created for images in Multichannel, Bitmap, or Indexed Color mode, 
because these modes do not support layers. In these image modes, type appears on the background as rasterized text. 
Photoshop also lets you set Asian text options. To do so, you must select Show Asian Text Options in the Type prefer­
ences.
