I created a 5 color vector design in Corel X6 and need a white base. I want to create a monochrome bitmap from my design and use it for my white base, I forget how so I need a refresher thump! thanks

okay I've added the art if that will help....

1) Click Bitmap>Convert to Bitmap>Grayscale 300dpi, Anti-aliasing checked and Transparent background checked

2) Click Effects>Transform>Invert
3) Click Bitmap>Color Transform>Halftone. Change angle and Maximum dot size to desired value or use the default.

The attachment has 45 degrees and 4 maximum dot size.

Okay, well that was easy.....thank-you very much.
Did you look at my art?

This is where I am unsure. I don't printthe shirts i just do artwork.
Will this work with 45 degrees and 4 maximum dot size?

What about 3 for the dot size.....just asking....thanks again

Wait a minute, I took the background coloroff as it was just reference..
Your's still looks different than my result....

Dot related concern will be determined by the mesh count of the screen used. Some say that moire effect is caused by the angle and recommends different angle based on what works for them. I can not recommend values one way or another. I can only show you how I would work on the artwork. May be someone with better recommendation will chime in.

Google for what's best for angle to minimize moire effect and maximum dot size relative to mesh count.

Desaturating to remove the color will have different effect compared to actually converted vector image to bitmap grayscale image. When transforming a desaturated color image to halftone r=the will result will be color halftone and not black and white halftone.

You have to convert the image to grayscale before converting it to black and white halftone.

The appearance may not look halftone as I in my image when it is zoomed out. Zoom the image to see the halftone effect better.

okay so i went the next step and went from grayscale monochrome to
black and white one bit monochrome......deleted the color(which) was white
and changed the outline color tooooo whatever color, let's say pantone green.
then I have a white base which is a spot color.....make sense?
I did zoom in and it don't look bad!
