Vector Text in Photoshop

Viewed in Photoshop (le), the text appears rasterized. It will image as pixels if printed

directly from Photoshop, unless Include Vector Data is checked in the print dialog (and the

printer is a PostScript device). If the le is saved as a Photoshop PDF (right), text is crisp

when viewed in Acrobat, and prints as vectors.

Shape Layers: To create a Shape Layer, choose a vector drawing tool,

such as the Pen tool, set the paths behavior in the Options bar to Shape

Layer ( ), and select a foreground color. Use the Pen tools and the

geometric tools (Rectangle, Ellipse, Custom Shape tool, and so on) to

create what are essentially vector masks for a layer filled with color. The

vector shapes can be edited with the selection tools and modified with

the Add/Delete Anchor Point tools. The rules for imaging Shape Layers

are the same as for vector text: to ensure crisp, vector edges, save the

file as a Photoshop PDF.

Shape Layers

Created with vector drawing tools such as the Pen tool and Custom Shape tool, Shape Layers

are essentially sheets of color with vector masks. is image has three shape layers; note

that each Shape Layer consists of a color component and a vector mask component, which

can be edited independently.

Vector Masks: Very similar to Layer Masks, Vector Masks are created

with vector tools such as the Pen tool. After a vector shape is created,

the user chooses Layer > Vector Mask > Current Path. The selected

path is then used as a vector silhouette for the layer, much like a

clipping path. As with vector text and Shape Layers, images with Vector

Masks should be saved as Photoshop PDFs to retain a crisp, vector edge

when placed in other applications, such as InDesign or Illustrator.

Smart Objects: Vector art placed as a Smart Object in a Photoshop

image receives special handling. While it displays as pixels, the source

vector art is embedded within the Photoshop file as vector. If a Smart

Object is scaled in Photoshop, the content is re-rendered from the

embedded vector information. Thus, no fidelity is lost from

interpolation during cumulative transformations. Raster art can also be

designated as a Smart Object, with the same benefits. But vector Smart

Objects differ in an important way from the vector components

discussed earlier: Smart Objects display and image as pixels, regardless

of how the file is saved. That is, saving as a Photoshop PDF does not

result in sharp vector edges; Smart Object content is rendered at the

resolution of the image.

Smart Objects do not retain any link to the original file; thus, any edits

performed to the original file won’t be reflected in the Smart Object

embedded in the Photoshop image. The Smart Object data is part of

the Photoshop file with no external links.

To edit a Smart Object, double-click its thumbnail in the Layers palette.

If the Smart Object is vector, Illustrator CS5 will launch, and the vector

art will open as an Illustrator file. Edit as

necessary, then choose File > Save; the edited data will be written back

into the Photoshop

file, and the Smart Object will be updated accordingly. If the Smart

Object is a pixel image,

double-clicking will open the image data in Photoshop for editing and

will write the corrected image data back into the parent image when

saved. Note that Camera Raw images can be placed as Smart Objects,
