Since traditional calligraphy is done using a flat baseline (horizontal) making it easier to read. Hand lettering, on the other hand is an entirely different school of thought which uses a variety of non-traditional composition treatments, with the lettering artists pushing the edges of the letterform while maintaining true to the base aspects of language, This hasn’t always been the case when it came to calligraphy. Calligraphy is an art form in its own right, although not as widely accepted as such.
If you’ve practiced blackletter calligraphy, you probably know what you’re looking at. with It’s spaced out lines that each consist of a descender line, a baseline, an x-height line, and an ascender line. Additionally, there are vertical guidelines throughout which can be useful to help reinforce the straight downstrokes.
Basically, all we’ve done here is slant the horizontal guides. while leaving the vertical guides at a 90º angle.In other words, horizontal strokes will slant at the new angle we’ve established, while downstrokes (like stems) will remain vertical at a 90º angle. This subtle warping adds a unique visual quality to the letterforms..
Since centering your text is difficult in the horizontal position. It will be more difficult to properly center your words when slanted, especially when your work consists of multi-lines of text. This is due to your letterforms being narrower in the slanted context, so you need to adjust this when plotting out the guide lines.
