A method for making a dot for dot proof for a printing device, such as a press, on another device, such as a proofer, the method including (a) inputting, at pixel level, binary or pseudo-binary data indicating at a given pixel screened colorant values of the printing device; (b) inputting contone colorant values of the printing device indicating a color in a neighborhood of the given pixel; (c) outputting colorant values for the other device at the given pixel, based on the input contone colorant values and on the input binary or pseudo-binary data, such that a color match is obtained with a given color behavior of the printing device.

The invention discloses a method for preparing a rot proof, heat proof, burn resistance and anti-corrosion composite coating on a light alloy surface, and relates to a method for preparing a composite coating on a light alloy surface. The method solves the deficiencies existing in the prior method for preparing the composite coating on the light alloy surface that the thermal protective performances, such as the heat proof and the burn resistance and the anti-corrosion performances, of the prepared coating are poor, or the binding force is poor, the coating is easy to scale off and out of work, and the quality and the thickness of the coating are difficult to be controlled. The method for preparing the rot proof, heat proof, burn resistance and anti-corrosion composite coating on the light alloy surface is performed according to the following steps: firstly, de-oiling and connecting; secondly, electrifying; thirdly; drying; fourthly, preparation of spray coating liquid; fifthly, coating and drying; sixthly, the repetitive operation of the step five, and thereby the rot proof, heat proof, burn resistance and anti-corrosion composite coating is prepared on the light alloy surface. The light alloy surface prepared on the light alloy surface has the properties of rot proof, heat proof, burn resistance and anti-corrosion, and the binding force of the coating and the basal body is high.

The invention relates to a preservative composition containing Chinese medicinal herbs and application thereof, belonging to the technical field of preservatives. The preservative composition is prepared by adopting the steps of: 1, weighting 0.1-0.78 percent of goldthread, 0-1 percent of the tuber of stemona, 0.1-0.84 percent of golden cypress, 0-0.58 percent of liquorice root, 0.1-1.5 percent of liquorice, 0-0.8 percent of poria cocos and 94.6-99.6 percent of water according to the weight proportion, uniformly stirring, soaking for 6-8h, heating to 110-130 DEG C, preserving the temperature for 30-50min, decocting, press-filtering, and collecting filtrate for later use; and 2, adding alcohol, which is 1.5-2.5 times the volume of the filtrate, in the filtrate, standing at a temperature of 4 DEG C for 24-26h, filtering out sediment, decompressing and recycling the alcohol at a temperature of 75 DEG C, carrying out rotary distillation and condensation at a temperature of 85 DEG C until the volume is 8-15 percent of the original volume. The prepared preservative is natural and non-toxic, has no residual, good rot proofing effect on the foods, refreshing efficacy, low production cost and wide application range, and is safe in use.
