5.1 In order to solve this problem a large difference on both sides of paper,China color felt pulp by adding fixative, and other measures to reduce the machine speed, decreased due to machine features two-sidedness of the more serious problems remain.

5.2 China color felt Production of paper and customers hue deviation pattern exists. Measures a) when the hue emphasis forebay to copy additional slurry to reduce the amount of dye; 2) lighter hue when the forebay to copy additional dyes;

5.3China color felt hue deviation, depending on the performance of the dye when necessary Hue remedy.

5.4 Use China color felt neutral papermaking additive color production on both sides of paper large difference in the production of green twisted due to a large difference in Jinan Lee Printing on both sides of the customer demanded the immediate presence at China color felt.

China color felt stop use acidic papermaking reduced sidedness, has been recognized by customers.

5.5 To reduce China color felt the frequency and change the paper too much scrubbing slurry tank, resulting slurry and downtime, change the order paper when the pre-arranged, the first production of dyes

Single, China color felt some of the light color, change the paper into pulp additional dyes can be a smooth transition.

5.6 plus the vividness of China color felt is poor, strengthen the control of moisture into the paper, adjust the cylinder temperature curve.

5.7 Production same batch of China color felt, sometimes because the slurry properties of hue deviation phenomenon occurs, in this case, only the strengthening process execution

Stability, in order to minimize the hue deviation. 5.8 production of different batches of paper,China color felt under the same circumstances in the process, there is often different hue. Analysis China color felt of reasons: 1) the dye properties; 2) Accessories differences in performance; 3) slurry performance differences.
