| Résumé : |
The reduction of dot gain in half-tone printing is desirable in order to accurately reproduce designs in printed format. An important contribution to dot gain is the spreading of ink on the substrate after image formation but prior to immobilisation by curing or drying. The spreading of a typical screen ink was modelled to determine the thermodynamic processes controlling the rate of drop spreading and the timescales over which they are significant. Suggestions are offered as to the characteristics desirable in polymer substrates in order to minimise dot spreading. |
