java bufferedImage 生成图片质量很差,图片局部细微锯齿化很严重.

[movi127]

小弟最近在做演出票打印工作.利用java中bufferedImage生成图片,但是图片质量不是很高,局部字体很严重,我该怎么处理?提高图片分辨率可以么?望各位大神给出建议,,不胜感激

public static BufferedImage generatePictrue(TicketFaceClass ticketFaceClass, TicketInfo ticketInfo) throws WriterException, IOException {

        PrinterImage.initGraphics(graphics, width, height);

//        画附券的分割线,及附券
        for (int i= 1 ;i <= ticketFace.getSubQuantity();i++){
            if(ticketFace.getSubAtleft()){
