Measuring ink concentrations in printed matter |
| abstract |
A method and apparatus for measuring ink concentrations in printed matter is described. The apparatus comprises: scanning means (105) for measuring the colour density of check points on a standard printed sheet (110) through a coloured filter or through a plurality of separate differently coloured filters and for measuring the colour density of points on a test printed sheet (106) corresponding to the check points on the standard sheet through the same coloured filter or filters; means for determining from the colour density measurements the concentration of the or each ink printed on the standard sheet (110) at each check point and the concentration of the or each ink printed on the test sheet (106) at each point corresponding to a standard sheet check point; and means for determining, for each check point and for the or each colour of ink, deviation coefficients representing the difference in ink concentration between the sample and test sheets. <IMAGE> |
