Spot color not printing spot color

[Jharris81]

So I want to print a sticker with just black, so I made sure that the graphic in illustrator was BK21A which is 100% K. Even shows up that way in Versaworks as the spot color but under magnification I can sure see magenta around the edges. I haven't worked to much with spot colors because I haven't really had to but is there something I need to change to make this happen. It's a very small graphic so I just wanted to do 100% K so I didn't have to worry about the head lining up just perfect. I am printing with max density profile.

it is probably down to your profile settings in versaworks. You can change this to density control only and it will print just using the black head without applying a profile to it

I know you can do this with density control but I figured if I used “black” BK21A it would but down just black in. Thought that was the whole point of spot colors.

In theory yes but sometimes weird things can happen when you export the file from illustrator and it changes it!

do you have convert spot colour ticked under file format in versa works rip, it wont honour the colour if you don't

I don't think I do. The image I uploaded were the settings I have and the check box is not checked. I'll have to check this weekend and give it another run. should that be check all the time?

Look at you spot color check boxes

Just send it 0-0-0-100 k
Why spot color?

Well I don't know if there is a difference but when the graphic in illustrator is selected for the color, it is 0-0-0-100 k. When I selected the color for the graphic I just used the Roland color library so that I didn't have any issues just printing straight black. Apparently I was wrong.

You can use the library, but then "convert spot color" needs to be selected. (In VW6 it's ticked by default, in VW5 it's not)
Just using 100% K only works, if you either set preserve primary colors(with any profile) or use density control only(no profile is used and images may look strange).

Are you working in rgb and not cmyk and saving as a .pdf
