Processing Images for TessJ4

Sample Image Being Given to Tessj4 for OCR

I am giving this image to Tessj4 and for whatever reason it cannot recognize this text as 0/0/0. Any recommendations as to how I can process the image or change my code to get tessj4 to recognize this?

Tesseract instance = new Tesseract();
instance.setTessVariable("user_defined_dpi", "360");
String result = null;
try {
    result = instance.doOCR(imageFile);
} catch (TesseractException e) {


Inverting the image (color) produced the correct results for me.
