Colour Blocks for Chart Corrections

[STATUE]

Going into Poole Harbour last week in the rain, my Admiralty Chart provided excellent pilotage, except the colour block I stuck on in the last 18 months.

It is now all blotchy with runs.

What paper that a normal colour printer will take, that can be stuck onto a chart and will resist rain?

AFAIK none, the ink is water soluble-as you found out. Sorry.

Spray your print with acrylic spray before you stick it on the chart. Comes in an aerosol for spraying artwork (fixing charcoal etc). Any craft shop should have it, or Amazon.

I haven't tested it, but it is possible to buy waterproof inkjet printing paper for printing maps etc. May be worth a go. I'll be interested to hear if anyone on the forum has tried it?

Nikwax map proof does the trick.

Or get someone to print the blocks out on a colour laser jet printer? The heat sealed ink is pretty waterproof as afar as I know.

The paper may be waterproof, but a lot of inkjet ink isn't!

Basically, waterproofness varies a lot from printer to printer, even within the same manufacturers different ranges. AFAIR - and I may be well out of date - we found that HP inkjet ink is waterproof, but I'm talking about the big 42" - 60" wide roll fed ones.

Another issue is UV fading. The standard inks for inkjet printers are NOT UV stable, and fade rapidly in sunlight. The blue especially fades rapidly. For professional models (e.g. Hp DesignJet range) you can buy UV stable inks, but most desktop printers only come with one range of inks.

For an ordinary consumer grade printer, I'd suggest that a waterproof spray is the best insurance.

I don't take charts into the cockpit - ever. for pilotage I take a pilotage plan I have transcribed onto a notepad, in a waterproof see through pocket.

Thanks everyone.

Aren't forums great, you've all given excellent guidance.

This is why I use Navonics on the IPad for close work. It lives in a waterproof case and the charts are allegedly up dated regularly. So far found it great - but I'm in the Med and it might not be so good in UK.
Never managed to find ink jet inks that wouldn't run if they got wet. I used to print off maps for battle field tours and always used a laser printer after the first time on a damp hillside in northern France resulted in folks trying to interpret a mud coloured bit of papier mâché.

Use a laser printer.
