When to use full sized coloured overlays
Full sized coloured overlays can be preferable to the smaller, more convenient reading rulers in a number of cases, either where factors of age (elderly or young), dyspraxia, or other disability cause co-ordination problems which make it difficult to move a reading ruler down the page to track text; or when both hands are engaged while text or other representations are being followed. Common examples of this use of tinted overlays are sheet music and knitting or other machining patterns. Overlays can easily be cut in half to use with smaller pages.
Disclaimer and guarantee: Ten colours are available. By experimenting with different combinations (guidelines are given on the pack of ten colours) it is usually possible to meet individual needs, although there may be a small number of individuals who would benefit from a tint that cannot be produced from combining the tints that we offer. If your overlays are not the colour you expected you may return them for a full refund, provided that they reach us IN UNUSED CONDITION within two weeks of our shipping date.
Glare and transparency
One side of the overlay has a matt coating. Some matt coatings can reduce the transparency of a tinted overlay, but overlays from Crossbow Education have been subjected to stringent testing to ensure that maximum print clarity is retained while reflected light from the overlay surface has been significantly reduced. Nevertheless, some people prefer using the gloss side of the overlay.
Overlays can be purchased three ways:
individually (£2.89+VAT)
Packs of 5 (any combination of colours) (£12.95+VAT)
Set of 10 (one of each colour overlay) (£23.95+VAT)
