To set up custom response HTTP header from a controller in Magento 2, use the following code:

** @var \Magento\Framework\App\ObjectManager $om */
$om = \Magento\Framework\App\ObjectManager::getInstance();
/** @var \Magento\Framework\App\ResponseInterface|\Magento\Framework\App\Response\Http $response */
$response = $om->get('Magento\Framework\App\ResponseInterface');
$response->setHeader('<header name>', '<header value>', $overwriteExisting = true);

** @var \Magento\Framework\App\ObjectManager $om */

$om = \Magento\Framework\App\ObjectManager::getInstance();

/** @var \Magento\Framework\App\ResponseInterface|\Magento\Framework\App\Response\Http $response */

$response = $om->get('Magento\Framework\App\ResponseInterface');

$response->setHeader('<header name>', '<header value>', $overwriteExisting = true);

For instance:

$response->setHeader('Content-Transfer-Encoding', 'binary', true);
