Magnesium Photo Engraving plate
Â
Â
Exposure
Halftone screen 9 is OK to obtain a correct exposure. For fine form, *1 is enough.
******0mJ/cm2Â is required for exposure.
Â
Â
Development
Put the exposed plate into 1% sodium hydroxide (NaOH) aqueous solution for ***0 seconds, or into 5% sodium carbonate (Na2CO3)
aqueous solution or Hydro-Solve developer concentrate for 1 minute, in temperature *00C,then take out the plate from the solution,
wash and wipe it with sponge in clean water softly.
Repeat above step to develop again if the plate is not clear enough.
Then dry it with compressed air or by absorbent paper.
A faster developing will happened while the solution was heated.
Â
Â
Â
Touch-Up
Touch it if necessary, no Burn-in is needed.
Weight
Record the weight in log.
Â
Â
Descum
Put the plate into 3% Nitric acid (HNO3) aqueous solution in room temperature and brush it lightly, then wash it with clean water.
Â
Â
Protect
To prevent oxidation, uniformly wet the plate immediately with Express Guard plate protector or Arabic gum aqueous solution before
clamping it on the lid of the etchin machine.
Â
Â
Etching
Follow the instructions by the machine producer to etch the plate.
Bath formula: Nitric Acid *1.8oBe *9% by volume
etch Additive 4% by volume
water *7% by volume
Machine data: paddle Depth ***0mm
paddle speed **0 rpm
starting temperature *8oC
plate holder **8 rpm
Etching speed: 1mm per 7 minutes for a new bath
The paddle speed and starting temperature should be adjusted according to the variety of the sidewall in the following etching process.
After etching, wash the plate with water or tri-sodium phosphate aqueous solution, then dry it.
Â
Â
Â
Replenish acid
Weight the plate to calculate the magnesium dissolved, then replenish Nitric acid accordingly, about **0ml Nitric acid corresponding
1 ounce of magnesium. Do not forget to check the dip gauge.
Top removal
Soak the plate in a *0% sodium hydroxide (NaOH) aqueous solution or in top remover concentrate solution in temperature *0OC
about 3 minutes, then remove and brush it with water.
