I have some b/w drawings done in pencil. I need to get them in photoshop and make it two colour, red and yellow for example, to give to a printer. I guess in layers. I'm not sure how to do it, is it easy?! The final result will be printed on an old photocopier but will appear screen printed.

a quick way.
-background with BW drawing > add layer in yellow, product mode.
-duplicate the backround > add layer with red, normal mode. create clipping mask. put the backround copy in lighten mode.

new channel > spot color

*sorry forgot one step :
once you've duplicated the bw backrgound > image >adjustment > invert.

You can make a duotone by going to image > mode > duotone (only works after your image is in grayscale mode). From there you can choose which colors you want to use and adjust how they're used.
Is this not what you want?
- duotones are intended to mix inks and create more than 256 levels of greyhorton

is that what you want?
horton : not used with channel / spot color, would be glad to know more ! :)

spot channels > think like layers:
just duplicate teh black and white art for each color into a new channel. select channel, find channel options off the side, change to spot color.
or paste from clipboard into a new sot channel.
pick your pms out of the color chip, adjust to 100%

It's easy with InDesign if you make each colour a separate grayscale file. Import to InDesign and add the colour there...

fuck me, it's like attack of the clueless here.
if you want to create a 2 colour job then you need to create a duotone. this can be done in 2 ways:
1: using the 'Image' navigation, choose "Duotone" - if the image is colour, you'll need to convert it to grayscale first. from here you can add the 2 colours, play with the curves and choose how the 2 colour interact.
2: using a greyscale image, add the colours as 'special colour' in the channel and create a multi channel artwork. this is probably not that useful in most situations but i've used it more with jobs that are mono or full colour and are using a special metallic or fluro.

http://www.creativepro.com/artic…also, it's important that you understand the file format you need to save the file as. for most it's a DCS (which uses the appedix '.eps' - as an eps is an 'encapsulated post script' meaning that the file is a container, holding all the pieces together that make up the file). DCS files can be saved with a preview both internal and external, colour, mono, seperate channels, combined file the lot so there's a little bit to understand but you'll have it down in 20 minutes.
you get better control of images by doing the duo in photoshop than illust or indesign 'generally speaking'. of course there are times when the opposite is true.

it's important to learn this stuff, as many design courses rush people through with so much to learn many younger designers don't know what they don't know.
i've seen files supplied to a printer here (i sublease) in CMYK mode but bright red and yellow (like the image above) and the job is a 2 colour. the designer couldn't understand that it's not 2 colour just becuase he used yellow and red. fucking genius.
- using either method (duo or channels) needs to break the file down to grey.airey
