11 Quality Assurance / Quality Control Understand the limitations of current knowledge, practice and technology Identify scope (10%? 100%) Work with originals in hand View at 100% (go higher if needed) Use targets to evaluate color visually Use histograms

Quality Assurance / Quality Control Control your environment Hardware configuration (RAM, processor, monitor) Software configuration (imaging, color management) Room lighting levels Human characteristics Clean your screen 12

Quality Assurance / Quality Control So, what are we looking for? Is the stroke adequately reproduced? Is the significant detail adequately reproduced? Is the fine detail in the darkest and lightest areas retained? Are there even gradations across the image? Is the image free of moiré effect? Is the significant ‘informational content’ adequately reproduced? Is the document fully reproduced? Is the image too dark or too light? 13
