Help creating a high quality print file from a sketch

Hi,
I have a basic program that draws a repeating pattern of sine waves and saves this as a tiff file.

I need to be able to output images that are large enough to print as backgrounds on sizes up to A1 but am struggling to be able to output anything this large.

Ive seen a few similar questions on the forum but am really struggling to apply it to my code.

Any help would be massivley appreciated

heres the code:

void setup(){

size(1500, 1500);

background (255);

float inc = TWO_PI/8.0;

for (int j=0; j<height; j+=200) {

float a = 0;

float prev_x = 0, prev_y = 100, x, y;

for (int i=0; i<width; i=i+4) {

x = i;

y = 100+j + sin(a) * 80.0;

line(prev_x, prev_y, x, y);

prev_x = x;

prev_y = y;

a = a + inc;

}

}

save("pattern.tif");

}

Any help would be great

heres my code

void setup() {

size(800, 800);

float a = 0.0;

float inc = TWO_PI/8.0;

float prev_x = 0, prev_y = 100, x, y;

for(int i=0; i<800; i=i+4) {

x = i;

y = 100 + sin(a) * 80.0;

line(prev_x, prev_y, x, y);

hi,
Ive used processign to a very minimal level before and am really struggling to generate code in order to draw patterns made out of repeating static sine waves. Any help would be much appreciated.

heres an example:
