This method for the calculation of Spot Colour Tone Value (SCTV) produces approximately uniform visual spacing of tones between substrate and solid. It can be calculated from spectral reflectance or colorimetric measurements of the solid ink, substrate and one or more patches of intermediate tones to be measured.<\/p>\n<h4>PDF Catalog<\/h4>\n<table border=\"1px\" class=\"des-table\">\n<tr>\n<th>PDF Pages<\/th>\n<th>PDF Title<\/th>\n<\/tr>\n<tr>\n<td><b>2<b><\/td>\n<td>undefined  <\/td>\n<\/tr>\n<tr>\n<td><b>6<b><\/td>\n<td>Foreword  <\/td>\n<\/tr>\n<tr>\n<td><b>7<b><\/td>\n<td>Introduction  <\/td>\n<\/tr>\n<tr>\n<td><b>8<b><\/td>\n<td>1 Scope <br \/> 2 Normative references <br \/> 3 Terms and definitions  <\/td>\n<\/tr>\n<tr>\n<td><b>9<b><\/td>\n<td>4 Requirements <br \/> 4.1 Calculation of spot colour tone value  <\/td>\n<\/tr>\n<tr>\n<td><b>10<b><\/td>\n<td>4.2 Steps for obtaining SCTV from spectral reflectance measurements <br \/> 4.3 Steps for obtaining SCTV from CIELAB measurements  <\/td>\n<\/tr>\n<tr>\n<td><b>12<b><\/td>\n<td>Bibliography  <\/td>\n<\/tr>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p><b>Graphic technology.
