I generate a pdf file with my html template for printer,but the color mode of output file was not supported for printer.especially the black color which presented in css was '#000000' ,but the cmyk color is not the pure black. 08255589fa902795fcbd6fbb08932be i can't figure it out.How can i output pdf file with cmyk color mode?

i figure it out. Cause my pdf page didn't have any other color except black and white,so i modify source code like this

@Override
public void setColor(FSColor color) {
//        if (color instanceof FSRGBColor) {
//             this._desiredPageState.fillColor = color;
//             this._desiredPageState.strokeColor = color;
//        } else if (color instanceof FSCMYKColor) {
//            this._desiredPageState.fillColor = color;
//            this._desiredPageState.strokeColor = color;
//        } else {
//            assert(color instanceof FSRGBColor || color instanceof FSCMYKColor);
//        }
        // todo 这里强制使用黑色
        FSCMYKColor fscmykColor = new FSCMYKColor(0,0,0,1);
        this._desiredPageState.fillColor = fscmykColor;
        this._desiredPageState.strokeColor = fscmykColor;
    }
