Spot Color/Bump Plate

Hello,

I was reading up on spot colors. And was confused about a term used

The passage:

You can also add an extra spot color (or bump plate) to a four-color CMYK image.

Can anyone please explain what is a bump plate? :confused:

could it be a spot color that indicates the trim outline? for example, an outline of a box print when it's cut to the shape and the extras are removed. good question, i'll try and find out.

Maybe they are talking about bump mapping?

I really have no idea, but maybe its for raised lettering? I know on a press you can have an extra spot or a gloss, but bump in not familiar with. Being a plate (and not the 5th color) thats my best guess.

i had a guess and it turns out i was right:

Touch Plate - An additional printing plate that adds a matched color to a process color image. (Also known as Bump Plate).

iow, you've got your 4 different plates for your 4 different process colors (cmyk), a fifth plate is added for the spot color.

Fig got it. :D

Spot colours use their own plates and not the CMYK ones. They are a precise colour that is mixed and catagorized from our good friends over at Pantone. That's why it's cheaper to do 1,2, and 3 colour print runs, you can get a specific colour that you want without slapping down 4 plates to create it. In my opinion, some of the best work out there has no more then 3 colours in it. You can also cheat and do duotones and overprinting and what not to create other colours. Of course overprinting is a complete crap shoot, but if you know what you are doing and are a bit lucky, you can get a third colour out of the two inks.

I would just like to add that spot colours are not limited to Pantone colours, or indeed TOYO or DIC etc. It is possible to mix your own spot colours and indeed most DTP packages these days also allow you to produce tints.

Outstanding..

Thanks for the defination fellas.

It really bothers me when I don't understand something, feels better now that I've got the answer.
