Due to the lack of possibilities to easily measure the consistency of the picture on the printing plate limited efforts are generally made to tune the reproduction of the printing plate. A study made by means of the newly developed Malcolm system, specially modified to also measure the characteristics of every printing dot on the printing plate, has revealed the benefits of scrutinising also the printing plate.
