The manual hinting process offers a broad range of on-screen optimisation possibilities – the effect of optimisation efforts depends on the character and technical restriction of the individual typeface. The main goals of XSF optimisation are:
- Consistency of horizontal levels (x-height, cap-height) within a font and throughout a family. Proper appearance of overshoots.
- Consistency of stem widths for regular, bold and italic styles.
- Pixel-per-em (ppem) sizes for stem widths widen to two, three, four or five pixels.
- Correspondence between thickness of horizontal, vertical and diagonal systems at different ppems.
- Removal of blobs on curved areas, crossing strokes, junctions and diacritics.
- Horizontal position of diacritics
- Screen appearance of symmetrical and nearly symmetrical characters.
- Controlled letter spacing. Spacing with uneven number of pixels in side bearings.
- Hand tuning of individual shapes and local aesthetics.
The difference between an “un-hinted” or an “auto-hinted” TrueType font and an XSF Font can be very impressive. ‘Clear as a crystal’- letters and a sophisticated appearance of the original design even in very small point sizes are typical attributes.
Custom Screen Optimisation
We have a library of XSF Fonts. In addition, notionally any font of the Linotype Library could be custom-engineered. Our basic TrueType or OpenType fonts can be customized with individual letters, self defined character sets or tuned to special applications (such as Microsoft® Word or Powerpoint). In every case, the original design is preserved to provide an maximum quality for on-screen appearance and traditional printing.
To reduce complexity, we offer four standard quality levels for on-screen optimization of fonts – depending on the customer needs. For further information or a quote, please contact us
